Yeh a 20 long will be fine for a long time, but eventually when they reach say 4+ inches personally I think they would enjoy a bigger tank, I plan on getting at least a 55 gallon or bigger in June next year when I get my tax return but for now im saving up hard for a car :grinyes:
As for my tank, i have very fine white gravel about 2 inches for substrate, a small piece of driftwood, a flower pot, and some rocks..the only real caves are the flower pot and the driftwood which is hollow and they like to swim through it. The male isnt actually nipping their fins he just chases them around alot when they enter his field of view..my plan was to wait for a pair to develop and then take the other females back to the lfs, so hopefully he stops being a bully sometime soon..theres a really nice pair of cons that are a touch over 6 inches at my lfs and their awesome..i want mine to be like that one day...
cheers..
