Keyhole Cichlid (Cleithracara maronii)
The Keyhole Cichlid is a peaceful and personable South American cichlid beloved for its gentle temperament and distinctive "keyhole"-shaped black marking along its side. Its subtle blend of tan, olive, and golden hues, accented by shimmering blue highlights on the fins, gives this fish a natural beauty that shines in planted aquariums. Unlike many other cichlids, the Keyhole Cichlid is remarkably calm, making it an excellent choice for peaceful community tanks.
Native to the slow-moving rivers and forest streams of Guyana and the Orinoco River basin, Keyhole Cichlids thrive in environments with driftwood, leaf litter, and dense aquatic vegetation. They are naturally shy when first introduced but become confident and interactive once they feel secure. Keeping them in pairs or small groups and providing plenty of hiding places helps bring out their natural behaviors.
Keyhole Cichlids do well in planted aquariums with soft substrate, driftwood, rocks, and subdued lighting. They appreciate clean, stable water and readily accept a varied diet of high-quality cichlid pellets, frozen bloodworms, mysis shrimp, brine shrimp, daphnia, and other prepared foods. A balanced diet helps maintain their health and encourages natural breeding behavior.
One of the most peaceful cichlids available, the Keyhole Cichlid is compatible with many community fish, including tetras, Corydoras, peaceful rainbowfish, hatchetfish, and other non-aggressive South American species. During spawning, they may become mildly territorial but rarely display the aggression common in many other cichlids.
