Red Devil Cichlid Breeding Guide

Breeding the Red Devil cichlid (Amphilophus labiatus), a monogamous substrate spawner that lays 600-700 eggs in a brood pit with biparental care.

Overview

The Red Devil cichlid, Amphilophus labiatus, is a large Central American cichlid endemic to Lake Managua and Lake Nicaragua, reaching about 25-35 cm. It forms monogamous pairs that spawn on flattened rocks or logs and provides advanced biparental brood care, but it is notoriously aggressive.

Sexing

Adult males develop a large bump (nuchal hump) on the head, which is much less pronounced in females. This difference becomes clear as the fish mature.

Conditioning

Condition a pair on a varied diet in a spacious, robustly decorated tank. Reported aquarium parameters are a temperature of 24-26 C, pH 7.0-7.5 and general hardness of 8-12 dGH.

Breeding Setup

Provide flat rocks or logs as spawning surfaces and a sandy bottom, since these fish are strong diggers. Because the species cannot be kept with other fish, breeding is best done in a dedicated species tank with ample space to absorb aggression.

Spawning Behavior & Trigger

The monogamous pair spawns on a flattened rock or log; the female lays 600-700 eggs that are then fertilized in a brood pit. Parents may relocate the eggs to another breeding pit several times.

Egg & Fry Care

The eggs hatch after 3-5 days. Both parents care for the brood, guarding and protecting the offspring. The fry can be reared on Artemia (brine shrimp) nauplii.

Common Challenges

The defining challenge is extreme aggression: red devils are described as very aggressive, will ram the glass at perceived intruders, can damage equipment and may even bite their keepers, especially when guarding a brood. Strong, fixed decor and a large tank are essential.
