Keyhole Cichlid

Native to the Orinoco river basin and coastal drainages of Trinidad and northeastern South America, the Keyhole Cichlid is one of the genuinely peaceful members of its family. The body is a warm sandy tan, sometimes with a faint yellowish flush, and the namesake marking is a dark blotch on the flank that in good specimens really does look like a keyhole. A bold black stripe cuts through the eye, giving the face an alert, almost curious expression.

These fish come from slow-moving, heavily vegetated blackwater and clearwater environments, so they appreciate soft to moderately hard water, slightly acidic to neutral pH, and lots of cover in the tank. Dense planting, driftwood, and leaf litter all help them feel secure. They're not demanding about exact parameters as long as conditions are stable, but softer, more acidic water tends to bring out their best color and encourages spawning.

Feeding is straightforward. They'll accept most sinking pellets, frozen bloodworm, brine shrimp, and small live foods without much coaxing. They're slow deliberate feeders, so make sure faster tankmates aren't outcompeting them at mealtimes. They rarely beg or dash to the surface, preferring to pick at food that drifts down to their level.

Behaviorally, Keyholes are famously docile for cichlids, and many keepers describe them as personable fish that recognize their owner and come to the front of the tank over time. They do take a while to settle in, spending the first few weeks hiding behind plants or under wood, but patience pays off. A bonded pair is a joy to watch, especially when they spawn and show off subtle parental behaviors.
