Diversity has created cichlid fish to be as sought-after as aquarium inhabitants. There are a lot varieties, as well as they're available in a variety of sizes, shapes and colors. Also there's the thrill of cichlids' behavior! In the early days of aquariums (around the year 1900) the aquarium had a small listing of New World cichlids being kept. The Chanchito ("Cichlasoma" facetum) was the first as was the fish called port cichlid (Cichlasoma portalegrense) as well as the Brazilian pearl eartheater (Geophagus brasiliensis).
