Old thread, I know, but probably better than starting a new one. I just wanted to add that I have an incidental culture of fairy shrimp in my tubifex/snail culture that seems to be growing well. It's a seven gallon acrylic hex with a UGF tube floating vertically stuffed with nylon mesh as a filter. I almost never change the water, in effort to make sure the bacteria remain numerous. Eggshell and mussell shells keep the pH up. I put a tiny amount of fish food in there daily, along with bits of leafy foods and tuna chunks. There are more turbo snails than anything else, a few ramshorn snails (the tiny kind) and a solid carpet of tubifex or detritus worms living in the snail waste. Swimming in this soup is a now rapidly exploding fairy shrimp population. I see them mating, and the weird nymph-like phases are kicking around looking more like daphnia than anything else. No daphnia, though. They died off in the first few weeks. This culture is about five months old. Anyway, I'd just confirm the thin-shelled (summer eggs) idea. My house is warm, which may or may not have anything to do with it, but I'm getting an army of these guys as we speak, which is good news for my surprise angelfish fry... So now comes the question...can I move this process to the fry tank? It would be great to have the fry living in the shrimp cloud!
I know this was old threat here, but have you already find out how to make continuous colony of the Fairy Shrimp producing Summer Eggs? Would like to know your research progress. Since I don't have any information yet on Summer Eggs.
