Scientific name: Aequidens maronii
The Keyhole Cichlid grows to four inches and should be kept only with other peaceful fish. These very gentle, almost timid, cichlids have an irregular blotch on the side that resembles a keyhole, and they sometimes change color when startled. The tank should contain plants and driftwood to provide security and hiding places for the fish.
A water temperature of 72º to 78º Fahrenheit, a pH in the range of 6.5 to 7.5, and slightly soft to moderately hard water are best. The Keyhole Cichlid will eat all flake and freeze-dried foods and should have an occasional feeding of live brine shrimp.
