Copadichromis Chrysonotus

Datasheet

General Description

Copadichromis Chrysonotus, a member of the Cichlidae family under Pseudocrenilabrinae, is an exclusive group of Malawian cichlids known as "Utaka". These fish are specialized in a pelagic lifestyle, commonly found in Lake Malawi. They exhibit unique feeding behavior with a protrusible upper jaw used to capture prey. While all species within the genus share this feeding habit, breeding strategies can vary significantly depending on the species, with maternal polygamous mouthbrooding being a common trait.

Aquarium Setup

Copadichromis Chrysonotus requires a spacious aquarium with plenty of swimming room. A sandy substrate is preferred, along with rock piles for variation and hiding spots. Adding hardy plants like Vallisneria, Anubias, or Sagittaria is optional, as these fish do not disturb vegetation. The recommended water conditions include a pH of 7.5-8.5, hardness of 10-25°dH, and a temperature range of 25-29°C (see table).

Behaviour

These fish are generally peaceful but do not thrive with aggressive tankmates. They are shoaling by nature but require space for males to establish territories. Maintaining a single male with multiple females is ideal to prevent female stress. Larger tanks can accommodate multiple males with a larger female group. Copadichromis should not be housed with Mbuna or similar-colored fish to avoid aggression.

Feeding and Diet

Copadichromis are specialized zooplankton feeders but adapt well to various foods in captivity. A diet of live, frozen, and dried foods is recommended, with Artemia nauplii being particularly nutritious. Offering vegetable matter like blanched spinach and Spirulina flakes is essential for a balanced diet.

Reproduction & Dimorphism

These fish are maternal polygamous mouthbrooders, displaying various spawning methods depending on the species. Males are larger, more colorful, and possess longer fins than females. Breeding pairs should be provided with a pH of 8.0-8.5 and a temperature of 75-78°F. Females carry eggs for 3-4 weeks before releasing the fry, which can be raised with newly hatched brine shrimp and crushed dried foods.

Habitat and Distribution

Endemic to Lake Malawi, Copadichromis Chrysonotus is typically found between Karonga and Monkey Bay. They inhabit deep, open waters in the lake, showcasing a specialized adaptation to pelagic life.
