I was reading several articles online about turquoise rainbow fish (I have a pair) and I was looking up potential tankmates for them when I move them to their new tank(currently have them in a 46 gallon-will be moving them to a 55 gallon or larger in a couple of months), when I came across several articles that suggested certain species of cichlids as tankmates. Some recommendations were... Firemouths, Jack Dempseys, some African Lake cichlid species. My question: Is this really possible?
