Keyhole cichlid Profile

The Keyhole cichlid, scientifically known as Cleithracara maronii, is a freshwater fish native to South America, particularly found in slow-moving rivers and streams throughout Venezuela and Guyana. It is predominantly brownish or greenish in color with a distinctive dark spot or 'keyhole' marking on its flank, which gives it its common name. This medium-sized cichlid grows to about 4-5 inches in length and has a somewhat oval, laterally compressed body shape, fitting for its habitat.

In the aquarium hobby, the Keyhole cichlid is known for its peaceful demeanor, making it a popular choice for community tanks. Its relatively calm nature and striking appearance, combined with its manageable size, contribute to its well-regarded status amongst enthusiasts. They are often recommended for hobbyists looking to keep South American cichlids without the aggression commonly associated with the group.
