Hey guys I inherited 6 Rainbows from a friend moving away. They are currently in my 20G long with my 4 german blue rams. They will all be going in my new 50G tank which is 36Lx18Wx15T (perfect footprint IMO) the Rams and the Rainbows seem to get along fine, what else do you think I could keep in here with them. I was thinking like 30 Neon tetras and a few corys. Tell me what you think.
