Hey guys I just set up my 5.5 RCS breeding tank and I needed somewhere to relocate the fish I had and I found a 16gal Green plastic bucket I put them in, so far it's just them and a little shelter hut thing. I was thinking about getting rid of the fish, adding sand/gravel. getting a heater and filter. some shelter things/rocks. What fish could I breed in here without the obvious livebearers or Betta?
