Origin

Herichthys cyanoguttatus is native to North America, primarily southern Texas in the United States and northern Mexico. They inhabit slow-moving rivers, streams, and reservoirs with sandy or muddy substrates and moderate vegetation.

Tank Setup and General Care

Texas cichlids require large aquariums with plenty of space. They are strong diggers and will rearrange decorations. Use rocks and sturdy décor to create territories. Sand or fine gravel substrate is recommended.

Plants are often uprooted, so hardy species attached to rocks may be used. Strong filtration is required, as these fish produce significant waste. Moderate water movement is preferred.

Temperament and Compatibility

Herichthys cyanoguttatus is highly territorial and aggressive, especially when mature. They should not be kept with small or peaceful fish. Suitable tank mates include other large Central American cichlids or robust species in very large aquariums.

Keeping pairs can be difficult due to aggression. Careful monitoring is required, particularly during breeding.

Food and Feeding

Texas cichlids are omnivorous and accept a wide variety of foods. Offer high-quality cichlid pellets as a staple. Supplement with frozen foods such as shrimp, bloodworms, and krill. Vegetable matter such as spirulina-based foods should also be included.

Avoid frequent feeding of live feeder fish. A varied diet helps maintain health and coloration.

Sexing

Males are typically larger than females and may develop extended fins. Mature males often develop a nuchal hump. Females are usually smaller and rounder.

Breeding

Texas cichlids are substrate spawners. The pair cleans a flat surface such as a rock before spawning. The female may lay between 200 and 1000 eggs. Both parents guard the eggs and fry aggressively.

The eggs hatch within a few days. Fry can be fed newly hatched brine shrimp. Parents may move the fry around the tank and guard them closely.

Care should be taken when pairing adults, as males may show aggression toward females. Provide hiding places and be prepared to separate the pair if necessary.

Lifespan

With proper care, Texas cichlids can live between 10 and 12 years. Large aquariums and stable water conditions help maximize lifespan.

Short Description

Herichthys cyanoguttatus is a large, aggressive cichlid from Texas and Mexico. This species requires a spacious aquarium with sturdy décor. Due to their territorial behavior, they are best suited for experienced aquarists keeping large cichlids.
