I want to set up another tank, and I need one that is small with fish that don't live too long (since I will be going to college in several years) and ones that I could possibly breed. The answer is obvious--Killifish! I'll admit I'm in love with the little guys already. The only problem is what to do with fry. Can you just get all females or all males, and then maybe add the opposite sex if you want to start breeding? Would it be too sinful to keep Killies without attempting to breed? Also, what would a Killie tank look like (as far as decor, plants, etc.)? Could you keep a few Cories with them? And once again, what to do with babies...do you think a fish store would take them? My only concern is that ignorant people will see colorful fish and use them as decorations until they kill them inadvertantly.
