I wanted a cool centerpiece for my tank. And a ram would definitely do just that, but as i keep my tank at 77.7, probably not a great idea, and at the time of a water change nitrate is usually up to about 10ppm, thats too much for a ram right? Its not always that, just what it builds up to before i change water. I think i saw people talk about kribensis being peaceful? Can a kribensis safely be kept in a tetra tank? I can lower or raise my temp if need be. Wether for a ram or kribensis. Are there any other cool dwarf cichlid type fish? Or maybe even just any sort of centerpiece fish?
