Liz, That is a great setup you must have for breeding all those things! I had a feeling discus might be one of the fish you were breeding, since they have gotten very expensive, plus there are so many varieties. I had a pair of them when I was 14 or 15, and got them to breed a couple of times, but back then it was harder to get the water to their liking, at least for me. African cichlids, which were fairly new back then, were my main breeders, and it was hard to mess the water up for them!
Glad to hear you have that great hobby, and that store there that makes it profitable for you.
