叉杯咽丽鱼 · Featherfin Cichlid

Overview

The long fins and adult colors of male Cyathopharynx furcifer come with demanding maintenance requirements. It is relatively delicate and needs excellent water quality and considerable space. Juveniles take time to develop the full male display.

Distribution & habitat

This Lake Tanganyika endemic occurs widely in transitional areas combining scattered rocks with sandy bottoms.

Aquarium setup

Use a few separated rock piles for caves while preserving extensive open swimming space and sand. A sandy floor and effective biological filtration are essential, especially because breeding males manipulate large areas of substrate. Hard-water-tolerant plants can be included and are generally unharmed.

Diet & feeding

Acceptance of many foods should not lead to a meat-heavy diet. Plant material should form the basis, using softened spinach, plain additive-free nori, and quality spirulina flakes or pellets. Avoid concentrated high-protein meaty foods.

Behaviour & compatibility

This active, relatively boisterous species needs more room than its size alone suggests. Yet stronger companions can intimidate it, causing withdrawal and loss of male color. Choose peaceful fishes able to hold their own, and avoid aggressive Mbuna. Separate related species and locality forms to prevent hybridization.

Sexual dimorphism

Males grow larger, show stronger colors, and have much longer fins, particularly the pelvic fins.

Breeding

Females mouthbrood, and several females per male help distribute pursuit. A male excavates a crater that may reach about sixty centimeters across, or carries sand onto a flat stone to build there. The female collects eggs immediately after laying. Egg-like structures at the ends of the male's pelvic fins contribute to the fertilization sequence.

Broods contain around ten to forty eggs and may be carried for roughly three weeks without feeding. Stress can cause early release or loss. Unless a female is being harassed, waiting at least two weeks before considering a move is advisable; long separation can also complicate her return. Released fry accept Artemia nauplii and finely crushed spirulina flakes.

Notes

Full male coloration depends strongly on growth and water quality. Preserve species and locality information instead of mixing young fish that initially appear similar.
