Natural habitat

The Convict Cichlid is found in a diverse range of environments in Central America, ranging from flowing rivers to still ponds and lakes. They prefer areas with cover, such as rocks and vegetation, rather than open water.

Where they are found

This species is native to Central America, particularly from Costa Rica to Guatemala on the Pacific slope and from Honduras to Panama on the Atlantic slope. Introduced populations exist in some areas of the U.S.

Aquarium care

In the aquarium, convict cichlids require a habitat that mimics their natural environments, including plenty of rocks and artificial caves for breeding. A minimum tank size of 75 liters (20 gallons) is recommended for a breeding pair. They are relatively easy to care for and adapt well to a variety of water conditions, although external filtration systems are preferable due to their habit of digging.

Feeding

These fish have a varied diet and accept most foods. It's best to provide a mix of high-quality pellets, flakes, and occasional live or frozen foods to ensure optimal health.

Compatibility

While convict cichlids can be kept with other species, their aggressive and territorial nature, especially during breeding, means they are best housed alone or with less aggressive species. The presence of breeding pairs can lead to conflict with tankmates.

Breeding

Breeding is straightforward as they are cave spawners. Provide suitable spawning sites such as caves, rocky overhangs, or clay pots. Breeding typically starts around one year of age, and they can lay 100 to 300 eggs at a time.
