小鳞丽鱼 · Emperor Cichlid

Overview

Adult Boulengerochromis microlepis are substantial fish predators reaching about fifty-five centimeters. Juvenile availability should not obscure the eventual requirements: public installations or exceptionally large private aquaria are the realistic long-term settings.

Distribution & habitat

It is endemic to Lake Tanganyika. Rocky rubble and open sand characterize many occupied zones. Nonbreeding adults often forage in open water, while juveniles use shallower sandy nursery areas with cover. Inshore feeding movements at night or early morning have been suggested.

Aquarium setup

A wild pair may defend at least five square meters, illustrating the scale required. Use a simple sand-bottomed enclosure with large stable rocks separating space. Place rocks securely on the tank base before adding sand because digging can undermine them. Excellent water quality and substantial weekly water renewal are essential.

Diet & feeding

Feeding changes with age: juveniles are omnivorous, whereas adults become predominantly piscivorous. Suitable prepared food can accompany live or frozen animal foods matched to size. Feeder fish are unnecessary and bring disease and nutritional risks.

Behaviour & compatibility

Fish too large to swallow are not necessarily attacked, but adult size sharply limits companion options. Juveniles may coexist peacefully before aggression increases with maturity. A formed pair generally excludes other fish from its territory.

Sexual dimorphism

Males are larger and more colorful.

Breeding

Maturity is reached at roughly forty centimeters and more than two years old. Spawning occurs on rock or in a depression, with the male fertilizing successive batches. Up to ten thousand eggs may be laid. Both adults guard the eggs through roughly seventy-two hours of incubation, then move larvae to another prepared pit until yolk absorption. Breeding demands exceptional space and rearing resources.
