I have an empty 10 gallon, and I'm looking for something to breed in it. Preferably something that an LFS will take, or I can sell on aquabid. I'm thinking about breeding some kind of shrimp maybe. Cherry reds and yellows are pretty cool. Will their offspring survive if I keep fish with them? Could I breed convicts in there? I think it's a bit small, but I've never tried. Can I even keep convicts with shrimp? I will have a 5 gallon for any fry as well. I can't upgrade to anything bigger, I already have a lot of weight on this second floor as it is.
