细体爱丽鱼 · Sardine Cichlid

Overview

The peaceful Cyprichromis leptosoma schools in open water and usually occupies the upper aquarium, complementing suitable rock- or shell-dwelling Tanganyikan fishes below. Numerous locality forms include blue- and yellow-tailed fish; mixing them can compromise breeding lines.

Distribution & habitat

It is endemic to Lake Tanganyika, using open water above transitional habitats of sand and scattered rocks. Wild groups can number in the thousands and feed on zooplankton.

Aquarium setup

Swimming space takes priority over decorative style. A deep aquarium allows rockwork to remain near the bottom while leaving upper water open. Secure the cover because displaying males can jump.

Diet & feeding

This small-mouthed zooplankton feeder needs appropriately sized foods. Although many items are accepted, live and frozen fare should form a substantial part of the menu. Watch new arrivals closely to confirm that every individual is feeding.

Behaviour & compatibility

Avoid boisterous Mbuna. Suitable Tanganyikan rock and shell dwellers can occupy different parts of the aquarium. Keep at least eight, with larger groups worthwhile when space allows; several males may then show full color. The group can also encourage shy companions to venture out.

Sexual dimorphism

Males are much more colorful than females.

Breeding

A male defends a three-dimensional open-water area against rivals while allowing females and other species through. Spawning occurs in midwater, where the female catches the eggs immediately. Egg-like structures at the ends of the male's pelvic fins participate in fertilization. Several females per male and a spacious, deep species setup improve opportunities to raise fry.

A female typically carries five to twenty eggs for as long as four weeks without feeding. Leave an unharassed female in place to avoid stress-related loss; prolonged absence can also affect reintegration. Natural release occurs near rock crevices. Young immediately accept Artemia nauplii and can usually remain with adults. Earlier artificial removal is a specialist method.

Notes

Large “Jumbo” trade forms may represent a different species. Separate forms and localities rather than allowing crosses. Wild fry sometimes gain protection within another species' brood, but this observation does not establish a captive mixed-brood method.
