点丽体鱼 · Blackbelt Cichlid

Overview

A bold dark vertical flank band marks Vieja maculicauda, a robust and aggressive large cichlid. Its predominantly plant-based natural diet does not prevent it from swallowing small fishes. Brood defense can be particularly intense.

Distribution & habitat

The range extends from Guatemala's Usumacinta basin through Honduras, Nicaragua, and Costa Rica to Panama's Chagres River. Still or slow river areas and lakes provide mud or sand, submerged roots and branches, and dense vegetation. Some populations also occupy brackish or fully marine water.

Aquarium setup

Use sand or fine gravel with substantial wood and root cover. Subdued illumination is suitable, and floating vegetation can soften the light. Adult housing must leave room for avoidance as well as territorial behavior.

Diet & feeding

Wild food is almost entirely plant-derived: algae, detritus, fruit, nuts, and aquatic or terrestrial vegetation. Maintain that basis in captivity while including some protein. A heavy-bodied appearance is not a reason to feed an exclusively meaty diet.

Behaviour & compatibility

Only similarly sized, comparably aggressive fishes merit consideration as companions. Small fish are potential food. Defending parents can become exceptionally aggressive, so earlier coexistence does not assure safety during brood care.

Sexual dimorphism

Males are larger and more vividly colored and develop a forehead hump at maturity.

Breeding

Breeding begins only after sufficient growth and maturity. Raising about six juveniles allows a pair to form naturally, after which other fish should be removed. Approximately five to six hundred eggs are laid on a flat stone and vigorously defended and cleaned by both parents. Hatching takes two to three days. Young are moved to prepared pits and become free-swimming roughly a week later.

Notes

Tolerance of saline habitats does not establish a need to add salt during ordinary freshwater care. The conspicuous body band is useful visually, but adult strength and changing brood-defense behavior are more important to long-term management.
