ok, im really gonna start getting into this breeding stuff, it is really interactive, more than just having decorations, and hey i might turn a few dollars right . so im going to buy a few smaller tanks ( 20's, 15's) to raise my fry in. but, in a little while when i get ahold of some money, i would like to find a fairly rare, not neccesarily hard to find, but rarely kept in aquariums, not many people have them kind of fish. the only tank im going to have available is a 29 gal. so i want a fish that a pair can be kept in a 29 gal, and is a unusually kept species, but not TOO expensive. any ideas???
