I have 3 Colombian shark cats that I will soon be moving into my new 77gal tank. I'm looking at many possible tank mates for them in the 77, but not too many, don't want to overstock. Are there any Cichlids that take well to Brackish water as my Colombians prefer? I've heard Krib's do well in Brackish, and don't get overly big. Any suggestions would be great. Also the tap water here is hard, so I don't have to fuss around with it much to suit Cichlids.
