Keyhole Cichlid

The Keyhole Cichlid is a rare gem among cichlids - a genuinely peaceful species that can be kept in community tanks. Named for the distinctive keyhole-shaped marking on their flank, these South American cichlids from the Guiana Shield are known for their shy, retiring nature rather than the aggression typical of their family. They have an attractive golden-brown coloration with black markings and a subtle iridescent sheen. Unlike most cichlids, Keyholes are non-territorial and will not dig up plants or attack tank mates. They are often seen hovering near their favorite hiding spots, darting out for food before retreating to safety. Their manageable size of 3-4 inches, peaceful temperament, and attractive appearance make them an excellent choice for aquarists wanting to experience cichlid behavior without the aggression. They are particularly suitable for planted community tanks where their gentle nature and interesting behaviors can be fully appreciated.

Care Requirements

Tank Setup

Keyhole Cichlids thrive in planted community tanks of 30-40 gallons. Provide plenty of hiding spots with caves, driftwood, and dense planting. Use soft substrate and ensure there are visual barriers to help them feel secure. Gentle filtration without strong currents is appreciated. They prefer dimly lit areas but will venture out once comfortable.

Water Quality

• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5
• Water Hardness: Soft to moderate, 2-12 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm

Feeding

These omnivores accept a variety of prepared and frozen foods. Offer flakes, small pellets, and frozen bloodworms or brine shrimp. They appreciate some vegetable matter in their diet. Feed once or twice daily with small portions. They may be shy feeders initially but will become more confident over time.

Behavior & Compatibility

Keyhole Cichlids are exceptionally peaceful for cichlids and can be kept in community tanks with other non-aggressive fish. They can be kept singly or in pairs. Their shy nature means they appreciate peaceful tank mates that won’t outcompete them for food. They are one of the few cichlids suitable for standard community aquariums.
