Boesemani Rainbowfish

Boesemani Rainbowfish (Melanotaenia boesemani) bring a striking contrast of blue and yellow-orange to a freshwater display. Mature males develop the strongest two-tone colors; females and juveniles are more subdued. Allow time for young fish to develop their adult appearance.

Aquarium & care

Plan for adults around 11 cm, with room for larger individuals. We recommend a spacious aquarium at least 4 feet long, such as a 55-gallon tank, for a group. Arrange plants around open swimming lanes, use effective filtration, and maintain regular partial water changes. Suitable conditions include pH 7.0–8.0 and moderately hard water, approximately 10–20 dGH. Confirm the stock’s holding temperature before acclimation.

Feeding

Provide quality tropical flakes or small pellets, supplemented with appropriately sized frozen foods such as brine shrimp or daphnia. A varied diet supports condition and coloration.

Temperament & tankmates

Keep at least 6–8 together. Usually peaceful but energetic, they suit similarly active community fish with matching water needs. Avoid very timid companions and aggressive predators.
