    Pardon my ignorance but.....

    Will you treat the display tank in any way? Are the parasites likely to have survived long enough in that tank as to cause new problems when you re-home your stock?

    No problem at all Dave, thanks for the question. Six weeks with the tank fallow should be long enough that all of the parasites will die off as they will starve and not complete their life cycle. If there are bacteria (the bad kind), my hope is that the immune systems of the fish can prevent infection, otherwise, I may be forced to treat the DT with an antibiotic. Time will tell. In the future, any new fish that I capture for the tank will spend 3 weeks in QT treated with copper.

    So far, day 4 of QT and the fish are doing well, and I don't think that they have a bacterial infection. I think what I was seeing was their slime coat giving off excess slime from two stressors, the parasites creating discomfort and also stress from being chased around by the dominant breeding male. Life it QT has quieted all that down now.

    I had to do a 50% water change as ammonia spiked (the QT is cycling) and add more copper to keep it at a therapeutic level. Last night, I had some leftover live bacteria in my fridge leftover and the expiration date is still to come, so I dumped it in the QT. It may work, but most likely the copper will kill the introduced bacteria. My hope is that it might speed up the cycling of the QT. I'd rather not do water changes so often so I can keep a stable treatment of copper. Testing for copper is crucial. Last night, ammonia was high and nitrite was zero. I have a sneaky feeling that I'll be doing another water change tonight.

    Quarantine is boring when it comes to watching my fish. Plus, my worry gauge is double what it normally is. That said, the fish are all doing fine. They look healthy, they're eating, they establish and maintain pecking orders, and defend territories, albeit zip tied pieces of PVC pipe. They were very skittish the first week and a half, but now respond to me during feeding time and don't flee during that time or during water changes, testing or treatment of meds. I guess that they're used to it. I have to wonder if any spawning activity will occur. Has anyone had that happen in QT while treating diseases?

    Regarding the treatment and disease status, the fish have completely stopped scratching since about the fourth day of treatment, and the white film and spots on the fish are gone. They all look fat and healthy, breathing looks normal. So, to be safe, I'll have them at least in QT for 2 more weeks with copper, then another two weeks for observation after I get rid of the carbon. By that time, the tank should be parasite free, as it would be fallow for six weeks. I'm 1/3 of the way there, and so far so good.

    The display tank is also a bit boring, although it is interesting to see more of the invertebrates than when fish are in there, specifically the crabs and bristle worms. The white thing is definitely a tube anemone and only fully extends after dark. When I turn the lights on, it draws back into a hole in the oyster shell. More jellyfish budding polyps have shown up on the same shells as the small anemones, if that is what they are. They could be another jellyfish species budding polyp, but I haven't seen any long tentacled jellies swimming around the tank. I have seen the short tentacled ones from what I know are the budding polyps, floating around in my tank. It's pretty cool, but I think that my power filters kill them off.

    Some of the tunicates died off, but about a dozen of them are still alive and feeding. The mussels are still alive as are the barnacles and open up to feed when I add plankton. But overall, the DT is a bit boring without the fish, although the grass shrimp constantly cruise the tank without the fish in there. I had one shrimp commit suicide as I found it on my tank top glass. I can't figure out how it jumped out of the only tiny hole, but it did.

    I only put the lights on for 4 hours a day, and cyano and other hair algae species have died way back, as have some of the other light dependent life, perhaps dinoflagellates? So the tank water is gin clear and the tank looks really clean. One month to go, and all will return to normal.

    So, what happens then? I will work on the big tank for sure, but also keep the 20g long QT tank set up just for that purpose, with the mummichogs to keep the tank bacterial population going and use it for new collections. I will use the 20g high for invertebrate collections as an observation tank, keeping it fishless and fallow, so that any invertebrates, shells, or anything else becomes parasite free before adding it to the display tank. And once the 100g is set up, the 20g long DT will become a macro tank, most likely for sticklebacks and other weed loving bay critters. All of my current fish will go into the 100g oyster reef tank.

    Future stocking list additions to the fish that I have now will include a hogchoker, a few more striped blennies, maybe one to three feather blennies, maybe some sheepshead minnows, perhaps a porcupinefish, and hopefully a tropical stray spotfin butterflyfish. My goal is to catch them all, but, I may have to purchase the last one if I don't have any luck finding any.

    I'm so happy that the QT process is going well so far. My nerves will be much more calm when I can return all of the fish to their oyster reef home.

    Thank you Dave.

    Here is the display tank, fishless (fallow) as it looks today. I keep the lights off but save a few hours each day and have reduced feeding to a tiny bit of flakes each day plus bottled plankton 3x per week, so much of the hair algae and cyano has greatly reduced:

    Video updates:
    First video of the QT, fish are doing well, doing what they do but in a pretty much sterile, copper treated environment with PVC pipes zipped tied for hiding spots:



    I'm pretty sure that this is a small tube anemone. It is bigger than the jellyfish polyps but smaller than the Ghost anemone. This guy is growing though, about 2x the size that it was when I first found it. It retreats to hide when I turn on the lights, so it is light sensitive. I may flip the oyster shell over once so it stays out when the lights come on, not sure yet. I doubt it is a worm, because it has too many tentacles, and don't seem feather like as most filter feeding worm tentacles appear.



    with the fish out of the display tank, the invertebrates and far less shy. Bristle worms come out to play a lot more these days. I believe that this species is commonly known as a clam worm. Here is one out foraging. I have yet to see one attack anything. They have a pretty nasty proboscis and will bite if handled (like bloodworms) but they seem to be very skittish. Even grass shrimp spook them, as you can see at the end of this video. I find them quite fascinating to watch. I'd say that I saw perhaps a half dozen different ones out at various times. There are many more tough, because there were at least a dozen that I could see along the edge of the tank glass in their burrows that never came out.



    Remember the tiny anemones that I thought that I had? Well, they never seem to grow any bigger than what I can see enough of with a magnifying glass. So, I have been observing more and more, looked at this video, and then researched, and found that they also are moon jellyfish polyps, just a different stage (before budding). So, I'd say I have about a dozen either budding or non-budding polyp moon jellyfish in my tank.


    Here's another moon jellyfish polyp:

    Update on my brackish tanks:
    In the 20g Long display tank, which is fallow, I finally got a good video of what I was trying to ID earlier, and I'm pretty sure it is a ghost anemone, but still could be a tube anemone. I'll have to study more about both to determine this. But, it's not a worm, definitely a cniderian. I am also ruling out that this is a jellyfish polyp, because it's much larger than those, and is growing, and has not changed to a budding polyp. It has been there for a long time also. Also, in the video, I found a small tunicate that I hadn't seen before just to the left of the anemone. I think that my tunicates are reproducing. This is the second one that I've found. I need to go back and look at older pics and vids to determine if this was there before or not.

    Also, the ghost anemone wasn't doing well in the 20g high. All of a sudden, it wasn't attached to anything, its tentacles were withdrawn, and it looked a bit withered. I did a water change and it looked a little better for a while, but then became detached again. So, I took the opportunity, since it wasn't attached, to move it to the 20g long display tank. It is attached to a shell now and is doing much better. The tentacles haven't fully extended yet, but the main body and overall health looks much better. I've wanted to move this creature to the display tank for a long time.


    The fish are in their last week of copper treatment, and are doing well. They're eating and look very healthy. After the last day of treament, then I will do water changes and add carbon to get rid of the copper. After that, I'll observe them in QT for a few weeks until the display tank fallow period ends, and then they get to go home.

    A couple more videos:

    The fallow display tank:


    A couple Harris Mud Crabs (Rhithropanopeus harrisii), one of two species in the tank. I always thought that these were a nasty muddy brown when collecting them in the field, but in a tank, they "clean up" really nice, and I find them quite attractive. They are very secretive though, but during the fallow period, when the fish are away, the crabs will play.

    The tank is doing well, as is the QT process. All of the fish are eating well and active, but they seem more aggressive right now. I'm not sure if it is due to breeding behavior, or just stress from a QT environment. As far as the fallow display tank, I found a third anemone on the underneath side of the oyster shell that the second anemone adopted as home. I thought earlier that they were tube anemones, but now I think that all three of them are ghost anemones. The one that seemed in poor health that I moved from the 20g high to this tank seems very healthy again. Here is a video of it below, sorry for the poor quality. I'll try and get a better shot of it in the future. The anemone moved from a razor clam across about 3" of sand to the base of the largest oyster cultch, and has stayed there ever since.


    I also found another unidentified invertebrate. I think it is some type of worm, but I'm not sure. It has moved to another oyster shell since this video, so it's not completely sessile. Here's a video of it:


    Most of the tunicates died off, but 3 of the larger original ones are hanging in there and seem to be healthy. I have two "new" ones that I've found that seem to be juveniles, about 1/4" wide now, one that I've found on an older oyster shell that I collected and also one on my cultch, which leads me to believe that they reproduced in my tank. The grass shrimp, mussels, barnacles, and the many bristleworms are also doing well.

    Looky what I found in my tank?







    This little snail shows up 6 months after my last collecting trip. I never saw any evidence of snails in either of my tanks. Last night, I saw it feeding on the side glass of the tank. It is tiny, and at first, I thought it was just a gas bubble from algal growth on the glass, but it moved... So, I zoomed in with the camera, and saw it was a gastropod, and took the video. I have no idea what species this is, and I assume it's a grazer.


    Why is this a big deal? I keep finding life in the tank that I haven't seen before, like this snail, and the third anemone that I didn't know that I had. Where the heck did this guy come from? I was wondering if things can be introduced via bottled store bought plankton? Anyone know? I've tried several kinds, the latest being Reef Nutrition Oyster Feast and phytoplankton...

    I have some new additions to the oyster reef system in my holding tank shown in the video below. On Saturday, I brought home two small four spined sticklebacks, Apeltes quadracus, two species of Ulva macroalgae, a few more sea squirts and a cluster of mussels, and two beautiful large ghost anemones. When I say large, I mean about as big as they get, about 1.75" wide at the tentacles, and about the same length for the base. These are also not pure white like the others in my display tank. Rather, they have a pinkish hue to them. Here's the video:


    The sticklebacks are feeding on small copepods and amphipods, but ignore my offerings. I guess I'll have to start raising some baby brine shrimp or buy copepods until these fish are big enough to eat the frozen foods. My plan is to keep them in this tank for a while, but move them into quarantine and treat them with copper. At that point, the holding tank (my 20g high), will be for invertebrates and macroalgae, and will remain fallow. After 6 weeks, then I'll move stuff to the display tank. If I go collecting and bring more stuff home, then that clock resets. The point is that I don't want to introduce ich to my display tank.

    Eventually, this summer, I hope, I'll have my big tank set up and all of the fish and invertebrates will move to that tank, except for the sticklebacks. I will keep the 20g long as a stickleback tank, with macroalgae as the dominant aquascape, with perhaps an oyster cultch or two (to be made later).

    After this weekend, all of my fish that are in quarantine will move to the display tank. I had a tragic death on Friday night, however. One of the female blennies went carpet surfing. I have no idea how she got out. My guess is that she jumped through the egg crate top that I had, because there weren't any other openings large enough for her to fit though. Now I'm down to 5 males and one female blennies in the tank.

    The fallow period is over and my fish are not out of QT and back into the display tank. While in QT, they were pretty much doing the same territorial chases that they've always done, defending their favorite piece of PVC pipe. But, after a few days in the display tank, the males established homes in their favorite oyster shells and really colored up into their spawning colors, pretty much like the one that I caught last week. Not only that, they're defending their 6" of space, all the while chasing, flashing, and harassing the female, I guess, to breed. It's weird though, like a love-hate relationship. They get all fired up and flash when they see here, then they both display side by side and shake (mostly the male), then he chases her away. Only, all of the males are after her like this. Her tail has been pecked a lot, and at one point was almost down to the caudal peduncle, but has since grown back some.


    The male spawning coloration includes a bright blue spot on the dorsal fin as well as a dark stripe and a yellowish/orange stripe along the front half of the fin. Also, they darken up their entire bodies almost to the point that their stripes fade away, their fins become tinted with orange, their pelvic and anal fins darken up and are trimmed with a white and black border, and their cheeks become and orange or peach color. You can really see this in the video that I'm posting below. That bright blue spot is quite pretty. The males are about 3.5 to 4 inches long now. In the six weeks that they were in QT, they grew quite a bit. It's hard to believe that it was less than a year ago that all of the fish were less than an inch and a half long.


    The female remains in the juvenile coloration, mottled with vertical bars and faint horizontal variable stripes. She is the smallest fish in the tank at 2.75 inches, but she is tough as nails.


    In this video, there are two scenes of a pair of males sparring over territory, presumably over a potential place to spawn and guard eggs. The first battle begins at the 3:30 mark, and the second one at the 5:02 mark. The video finishes showing the object of their affection, a female striped blenny.

    Tank update: I noticed that the fish in the 20g long were breathing heavily, mostly due to constantly defending their territories, but after a couple water changes to clean up detritus, I decided to also add an airstone. I also cleaned the HOB filter and powerhead and now there is much more flow. As a result, the fish are out much more and much more photogenic. While cleaning the filter, I discovered several tunicates in there, and also some inside some of the oyster shells. My original ones all died, so I assume that these are progeny. The three small anemones disappeared since I added the fish. I don't know if the fish killed and ate them, or if they simply moved or are hiding. In fact, all of the invertebrates except for the shrimp rarely come out (crabs, worms, etc.). Their vacation is over! Time for some pics...

    Male striped blennies battle over oysters and the lone female. The blenny that I dubbed "King" is on the left. He pretty much rules the roost but the one on the right holds his own and sometimes wins these battles

    The next couple pictures show King sporting his spawning colors: the bright blue dorsal fin spot, the dark anal fins trimmed in black and white, the yellow/orange dorsal fin stripe, peach colored gills and mouth, and orange trimmed pectoral and tail fins. Notice how dark King gets in the above picture during the standoff.

    The object of their affection, the lone female in the tank. Notice the drab coloration. She is quite a bit smaller too. The males chase her constantly, nipping at her, and sometimes shaking their bodies. I suggested to them that they take a nicer approach to courting, but it's hard for them to break bad habits.

    My blennies spawned, probably on Friday. I didn't see the spawning activity, but was wondering why I wasn't seeing one of the largest males. The reason he wasn't out and about was because he was guarding eggs. He does make quick trips to come out to eat during feeding time, but goes back and forth between the oyster shell and the food.

    Here's a pic of him guarding the eggs. You can see the eggs and also the female to the right hanging out. He is tolerant of her, but still chases her off if she hangs out too long.

    Here is a pic of the shell and eggs that he left to chase off another fish:
    Click here to enlarge

    Here is a cool video of him guarding the eggs. There is another male that challenges him, not for his eggs, but rather to defend another oyster shell that he is claiming as territory. This is interesting, because he is somewhat smaller and not even a week ago the two larger males were picking on him pretty bad. Now he fights back and stands up for himself. My guess is that he's claiming his own spawning location:

    So the female striped blenny is very brave, despite being smaller than all of the males. She struts about the tank and gets chased and harassed by all of the males. But, she keeps doing her thing. However, sometimes the chasing is more like corralling. Normally, a male will chase and bite her to scare her away, as he does rival males. However, when he wants to breed, he chase, nip, or sometimes push her to get her into his oyster shell, while at the same time positioning his body between her and the escape routes away from his shell, while shaking (flashing), with fins erect and displaying his colors to her. This is an attempt to push her into his oyster shell. I saw this happen a couple nights ago, and ran upstairs to get my phone. But, by the time I had it set on my tripod, another male blenny chased her off. He actually kept her from going near the other male, although probably not on purpose, rather, just to chase her away.


    Meanwhile, another male on the other side of the tank had a different approach. He would just come out of his oyster shell and position himself higher on the reef above her, and kept doing that until she got close to his shell and eventually she would enter. He would follow her in and then she’d shoot out and swim away until this started all over again. He was so close! It was so fun to watch that I was down there from 10 PM until well after 1 AM watching this, trying to get a good video and/or pics. They never seem to behave the way you want when the camera is pointed at them.


    Also, the territorial battles between the males and their shells is fun to watch in itself. Most of the time, the skirmishes are just all show. Sometimes, albeit rarely, they trade bites and even take chunks out of each other’s fins!


    However, last night, I was able to capture some of this drama on film. Instead of one male doing this, three of them were competing for her! One of the males actually pushed her half way across the tank toward his shell, but she got away. I'm not sure if I got that on film or not. It's not in this video, but maybe I caught it in another one. I have to go through those videos to see if I can find if I caught it or not. Anyway, this is the best video of the action so far, especially the first third of the video. I can watch them for hours!

    Is there a reason why you are keeping the male:female ratio you have? I would expect species that exhibit this type of behavior to be kept in a harem type of ratio with one male to every three or four females.

    That's a good question, thank you. I had 2 females but one of them went carpet surfing while in QT, so now it is 5-1. When I collected these fish last year, they were juveniles, all about an inch long except for the largest one that was 1.5" long. The juveniles all looked the same until they reach about 1.5-2" long and then they start to resemble their sexual dimorphism forms. In fact, as juveniles, the coloration is identical to the females. I had no idea what male to female ratio that I had until about January of this year, when it was clear that the smaller fish wouldn't change colors and were thus females (the males grew much larger). The funny thing is that, at first, I thought that I had more females than males, and was worried that I didn't even have a pair!

    Females of this genus of combtooth blenny tend to visit more male oyster shells to lay eggs than just one, based on what I've read and what I've observed. Also, males will allow different females to visit their shells and lay eggs, even if eggs are already being tended in their shell. My goal is to even up the ratio a bit over time, but right now I'm limited by tank size. So, until I get my 100g set up, I may only add one more female to take the pressure off of the other one.

    Also, in the wild, males establish territories based on finding a suitable empty oyster shell. Chasmodes males seem to be more tolerant of each other than other combtooth blennies as their territories might only extend about 6-8" from their favorite shell.

    One more thing that amazes me, is how fast they grow. My guess is that at 1" long, they were probably broods from last September or maybe October. The males grew from 1" long to almost 4", now full adult size and spawning, in less than a year. I collected them last June.

    I have some exciting news! After I got home from work, I went down to my tank to feed the fish and noticed that one of my skilletfish wouldn't leave his clam shell to come up and stick to the glass and beg for food. So, I shined a flashlight inside the shell, and when he moved away, I saw eggs on the upper shell half! He was guarding eggs and only feeding on food drifting by his shell. I made a point to plunge my hand into the tank in front of him with a pinch of frozen food, and he ate after a little bit of coaxing. It was weird because the other day, I only could find three skilletfish coming out for food, and I searched the tank high and low with a flashlight and couldn't find the fourth one. At that time, there were no eggs in any of the shells. So, apparently, the female skilletfish was the one that I couldn't find, and she was probably somewhere near the clam shell out of my view the entire time. I took a video of him guarding and fanning the eggs. I found it entertaining. Hope you all do as well.


    Also, the gobies are acting differently, constantly flaring their fins and chasing each other, so my guess is that they will be next. The female blenny is about due to spawn again as well, as she is getting very plump.

    Yes, I did. In fact, all three species of fish are breeding regularly now. I have fry swimming at the tank surface just about every three days or so. The skilletfish lay eggs that often for sure. The gobies lay eggs about once every three weeks. And the blennies about once every two weeks. The fry of each look slightly different, but it's difficult to tell what they are without a microscope.

    Here's a video of the male and female skilletfish spawning:


    Here's a video of a male goby guarding eggs:


    And a video of the babies of one of the species...not sure which one. Skilletfish maybe?


    But, I haven't been able to keep any alive for more than three or four days. I've tried feeding them bottled, plankton/oyster eggs and baby brine shrimp, but so far, no luck. I thought that maybe predation from other adult fish might be an issue, so I tried keeping them in a breeder net, but still lost them. I think the problem is a combination of starvation and predation. I guess the solution to raising them is to build a grow out tank system and also raise live food (like rotifers), etc. For now, I guess it is free fish food.

    Are the BBS too big for the fry? While rotifers are a standard, I would be looking at vinegar eels or grindal worms depending on the necessary size. Neither of those need a greenwater culture to feed to food. If the fry are really small, paramecum are pretty easy.

    Thank you Nil! I haven't tried live BBS yet, just frozen ones and that didn't work. I need to set up a tank to grow out the fry. In the meantime, they keep churning out more fry, LOL.
