三斑丽体鱼 · Three Spot Cichlid

Overview

Cichlasoma trimaculatum is a large, colorful cichlid with a distinctly aggressive disposition. Its habit of rearranging the aquarium makes territory layout important. Effective filtration is needed, but should not expose the fish to a concentrated strong current.

Distribution & habitat

It is native to western Mexico, Guatemala, and El Salvador, with feral populations in Singapore. Slow waters of Pacific coastal plains and nearby lowlands provide mud or sand substrates among submerged roots, branches, and vegetation.

Aquarium setup

Use rock and wood to divide space, allowing for the fish's tendency to move and rearrange furnishings. Rooted plants are likely to be uprooted. Large fish can be messy feeders, so provide capable filtration while dispersing its return through a spray bar or similar arrangement. Avoid powerful direct flow.

Diet & feeding

This predator naturally eats other fish and aquatic as well as terrestrial invertebrates. Both predation and aggression matter when considering any companions.

Behaviour & compatibility

Tankmates are not easily tolerated. A very spacious community of robust cichlids may work, but success is uncertain. Defense of a spawning area becomes particularly vigorous.

Sexual dimorphism

Males are larger and may show stronger color.

Breeding

A pair generally selects a flat stone for spawning and may deposit around one thousand eggs. Established pairs are usually fairly straightforward to breed. Both adults defend the eggs strongly and continue caring for the young after hatching.

Notes

The species is believed to have contributed to flowerhorn hybrid breeding. That possibility does not alter the needs of the natural fish, whose adult size and territorial behavior should guide long-term planning.
