Natural habitat

Boesemani Rainbow Fish thrive in well-oxygenated waters rich in minerals, typical of the slightly alkaline waters found in their native habitats of Ayamaru Lakes and nearby rivers in West Papua, Indonesia. These fish prefer stable conditions and exhibit vibrant colors in optimal environments.

Where they are found

This species originates from Indonesia's Lake Ajamaru and nearby lakes in West Papua, where it occupies both still and flowing waters with abundant aquatic vegetation.

Aquarium care

Create a habitat that mimics their natural environment with plenty of vegetation, open swimming space, and soft substrates. They require stable water parameters, with a preference for well-filtered, clean water that is not overstocked.

Feeding

A balanced and varied diet is essential for Boesemani Rainbow Fish. They should be fed high-quality flake and micro-pellet foods, supplemented with protein sources like bloodworms, brine shrimp, and daphnia, along with vegetable matter such as spirulina and blanched greens.

Compatibility

Generally peaceful, but males can be aggressive towards females during spawning. Provide ample cover to minimize aggression and ensure a stable community tank.

Breeding

To breed Boesemani Rainbowfish, use a separate breeding tank with soft, slightly acidic water and fine-leaved plants for egg scattering. Conditioning the fish with high-quality foods is critical for successful spawning, followed by careful management of the fry.
