Placidochromis phenochilus

Common Name: Star Sapphire Cichlid

Scientific Name: Placidochromis phenochilus

Family: Cichlidae

Origin: Lake Malawi, East Africa

Overview:

Placidochromis phenochilus, widely known as the Star Sapphire, is one of the most visually striking Lake Malawi cichlids. Famous for its deep blue coloration and shimmering white “star-like” spots, this species is highly prized by aquarium hobbyists looking for a bold yet relatively calm Malawi cichlid.

Appearance:

Adult males develop an intense royal to sapphire blue body covered in bright white or pale blue spots, giving the fish its signature “starry night” appearance. Females and juveniles are more subdued in color, typically silver or gray. Adults reach about 9–10 inches (23–25 cm) in length.

Behavior & Temperament:

The Star Sapphire is considered semi-aggressive and generally calmer than many Mbuna species. Males can be territorial, especially during breeding, but overall they are well-suited for mixed Malawi tanks with similarly sized Haplochromine and Peacock cichlids.

Diet:

In the wild, P. phenochilus feeds on small invertebrates found in sandy substrates. In captivity, it thrives on a diet of high-quality cichlid pellets, supplemented with frozen foods such as mysis shrimp or krill. A balanced diet helps maintain color and health.

Habitat & Tank Setup:

This species naturally inhabits deep sandy areas of Lake Malawi. An aquarium should provide a sand substrate, open swimming space, and some rock structures for territories. Strong filtration and stable water conditions are essential.

Reproduction:

Placidochromis phenochilus is a maternal mouthbrooder. After spawning, the female carries the eggs and fry in her mouth for several weeks until the fry are ready to swim freely.

Why Choose the Star Sapphire?

With its stunning coloration, elegant swimming behavior, and manageable temperament, the Star Sapphire is an excellent showcase fish for larger African cichlid aquariums.
