Well, TC, I read all the websites you pointed out and have pretty much concluded I have a male. Now what do I do?? One place I read says it is hard to find a female because stores usually only stock males. But I also read they like to be in groups and will pair up. If you can't buy females, am I suppose to find a gay male, lol? Or is he doomed to be a loner? This whole aquarium business is getting more complicated than I remember it being when my kids were growing up! I only have a 16g tank and every fish I pick can't be in a harem, school or sorority either.
