The three spot cichlid or trimac, Cichlasoma trimaculatum, is a large cichlid from western Mexico, Guatemala and El Salvador. It lives mainly in sluggish waters of the Pacific coastal plains, among roots, branches and vegetation over mud and sand. A fairly aggressive fish that grows to around 40 cm, it is believed to be one of the species used to create the flowerhorn hybrid, and both parents guard the eggs and fry.
Distribution
EditWestern parts of Mexico, Guatemala and El Salvador. There are also feral populations in Singapore.
Habitat
Write a noteEditFound mainly in sluggish waters of the Pacific coastal plains and surrounding lowlands. It tends to be associated with soft substrates of mud and sand, where it lives among submerged roots, branches and vegetation.
Aquarium size

Maintenance
Write a noteEditRocks and bogwood to form territories. Lives in lakes and slower moving water in the wild, so avoid strong current in the aquarium. Plants are best avoided as the will be uprooted. Trimacs will rearrange the tank as they see fit!

Diet
Write a noteEditA predatory species that feeds on other fish and both aquatic and terrestrial invertebrates.
Behaviour and compatibility
Write a noteEditA fairly aggressive cichild, the trimac will not tolerate other tankmates easily. It may be possible to keep this fish as part of a large robust cichild community if enough tank space is provided.
Sexual dimorphism
Write a noteEditMales is larger and may be more colourful.
Reproduction
Write a noteEditBreeding is fairly easy. The pair usually select a flat stone and spawn on that. Up to 1000 eggs may be laid. Trimacs make excellent parents and will guard the eggs fiercely. Both parents will also tend the fry when hatched.
Notes
EditCichlasoma trimaculatum is a large colourful cichlid, if a little aggressive. It is believed to be one of the fish that was used to create the hybrid Flowerhorn cichlid. We prefer it in its natural state.
As with most large cichlids they can be fairly messy eaters so ensure decent filtration is provided. It is recommended to use a spraybar to disperse the water returning to the tank as trimacs will not appreciate strong flow.
