I would try it, if you are into that. One of my wife's and I's new tanks is a 55 gal. with peaceful fish. She has got some platies breeding in there. She's got some tetras, a dojo loach, cory cat, farlowella cat, chinese algea eaters, and some more I can't think of at the moment. Its a fun tank to have because there is alot of movement in the tank, especially the chinese algea eaters. Those guys are fast.
