Description
Overview:
The Jantan Boesemani Rainbowfish ("Jantan" meaning "male" in Indonesian/Malay) is a vibrantly colored freshwater fish, prized for its brilliant split coloration—a glowing blue front half fading into a fiery orange or yellow back. Males exhibit the most intense colors, especially when kept in groups or during courtship. Active, peaceful, and hardy, Boesemani Rainbows are a favorite centerpiece in planted and community aquariums.
Origin:
Endemic to Lake Ayamaru and Lake Hain in the Bird's Head Peninsula of West Papua (Indonesia). In the wild, they thrive in clear, alkaline freshwater lakes with dense vegetation.
Feeding:
Omnivorous and enthusiastic eaters. Feed a varied diet of high-quality flake or micro pellets, frozen or live brine shrimp, daphnia, and bloodworms. Supplement with vegetable-based flakes or spirulina to maintain vibrant color.
Tank Mates:
Peaceful and best kept in schools of 6 or more, which enhances color and reduces stress. Ideal tank mates include other rainbowfish, danios, rasboras, Corydoras, and peaceful livebearers. Avoid slow or long-finned fish that may be outcompeted for food.
