Unfortunately he eventually died but it was not immediate, lasted for quite a while. I tired a couple of medicines and a new tank with fresh water but this did not change, maybe it had a damaged or ill formed swim bladder or I just didn't find the solution.

When I first saw them I thought they were just for little kids and would not want those "fake fish" but now I think they look cool, I don't have any in my tanks yet, but plan to try them out soon for a little color balance. I think it's far better than breeding fish for a deformity that it is aesthetically pleasing to a human. I have no problem with most genetic modifications, adding color to a fish will have no detrimental effect to the fish in an aquarium. It might even be better than selective breeding (likely inbreeding). I could see some who want to keep a natural aquarium with natural looking fish, there are a lot of fish that would be off their list including almost all guppies and endlers. I'm not in that boat, but more power to them. I think its just preference as long as it isn't harming the fish. I have more of a problem with something like the Gold Roseline Barb where a certain % of are blind. While a very cool looking fish, I balked at getting them once I learned that the side effect was blind fish. Hope they can reduce that deformity some day.

I do think the marbles helped, I would have still had some but this kept them from getting nearly any of the eggs. My water is pretty hard but I collected a lot of rainwater in March just to try to breed the tetras and rasboras. I'll convert the fry to harder water through water changes. I only had 5 neons left so I may have been dealing with only 1 sex, kind of hard to tell when they get full size. I may try to chronicle, I'm a bit inconsistent with my time and pictures. Nice breeding projects, how hard is it to get the rainbow shiners to breed?

Curious to hear about others success. I am actively trying to stop my live bearers from breeding and failed at breeding neon tetras. I took a stab at documenting it in a 2 min video. https://youtu.be/wQ6so4XUoGQ

I wish I had one near me, they sound fun. I'd have to drive a couple of hours to get to one probably. But I have bred up a few things.

I put them in my tetra tank and they didn't last 3 seconds. A treat for slightly bigger fish.

Found several in my tub when starting to clean it. Not sure if these eat fry or shrimp but they aren’t very big, only 1/2 an inch. Hoping they aren’t dragonfly larvae.

Yeah, I breed CPDs regularly and I've tried the same method a couple of times with tetras to no avail. I just found two baby fry in a gravel vac bucket, not sure what they are yet. Hope I can grow them up to find out. It's definitely not an efficient way to do it but I thought I would give it a try.

I was wondering if anyone has tried gravel vacuuming a community tank where they have tetras or other egg scatterers and then just putting the gravel vacuumed water in a tub, bucket or other tank to see if any hatched over a few days. I've seen neon tetras and other species spawn in my community tank and know they have zero chance of hatching and survivng all the hungry mouths. I just wondered if anyone else has tried to salvage unseen eggs. I'm not sure the eggs would survive with all the mulm though.

I enjoy CPDs. They are fun to breed raise and watch their interactions in a large community tank of small fish.

Tiny tanks and the poor fish who have to live in tiny tanks their whole lives. It would be pretty sad if your whole life was spent in one room.

Does the purigen reduce nitrates?

I want to try tetras for the summer but I am afraid my weather is not stable enough, it can get 95 high and 45 low in the same day. I might just pick a ricefish or two and let them stay out year round.

Adults are fine just the newborn shrimp may be picked off.

I currently feed twice a day but wanted to increase the frequency to increase growth. Does anyone have experience with how frequently they can be fed, I was thinking 4 hours. I'm not sure how long it take for them to digest their food.
