Texas Cichlid Breeding Guide (Herichthys cyanoguttatus)
Overview
The Texas Cichlid, Herichthys cyanoguttatus, is a robust substrate-spawning cichlid native to North America. It forms monogamous pairs and shows excellent biparental care, making it a rewarding but aggressive breeding project at intermediate difficulty.
Sexing
Adult males tend to be at least a couple of inches larger than females and develop pointed extensions to the dorsal and anal fins. Some males also develop a nuchal hump as they mature. Before spawning the female's ovipositor becomes visible.
Conditioning
Condition the pair well to bring the female into spawning condition. Courtship can be prolonged and sometimes violent, involving tail slapping, lip locking and gaping by both sexes, so a spacious tank with sightline breaks helps reduce damage.
Breeding Setup
Provide flat rocks or stones as spawning sites. The pair selects a site and cleans it thoroughly before the female deposits eggs on it.
Spawning Behavior & Trigger
The female lays a line of eggs and moves aside so the male can fertilise them, repeating in several batches. Clutches may number several hundred eggs.
Egg & Fry Care
Parental care by both fish is excellent, and both parents retrieve straying fry. Eggs hatch in 2 to 3 days, and the fry remain in a pre-excavated pit until the yolk sacs are absorbed, becoming free-swimming after a further 4 to 5 days. Free-swimming fry accept Artemia nauplii and should receive 2 to 3 meals per day; crushed flake and cichlid pellets are added as they grow.
Common Challenges
Aggression during courtship and brood defence is the main hurdle, and incompatible pairs can injure each other. The species reaches a large size with a high bioload, so generous tank volume and strong filtration are essential.
