Diet for Banded Rainbow – Batavia Rainforest
In their natural habitat, M. trifasciata feeds on insects, crustaceans, and plant matter. In captivity, provide a varied diet including high-quality flakes, micro pellets, frozen or live foods such as daphnia, brine shrimp, and bloodworms. Occasional vegetable supplements like blanched spinach or spirulina enhance colouration and digestive health. Feed small portions two to three times daily to match their active metabolism.
Aquarium Setup Banded Rainbow – Batavia Rainforest
Aquarium Filtration
Use strong biological and mechanical filtration to maintain clear, oxygen-rich water. Gentle to moderate water flow mimics rainforest stream conditions and supports natural swimming behaviour.
Aquarium Plants
Incorporate robust plants such as Vallisneria, Hygrophila, and Java Fern, arranged densely at the back and sides to provide shelter while leaving open areas for shoaling. Floating plants soften light and offer additional cover.
Aquarium Lighting
Bright, full-spectrum lighting accentuates the vivid colours and horizontal bands of the Banded Rainbow. A consistent photoperiod of 8–10 hours is recommended.
Aquarium Heating
Maintain temperatures between 24–28°C with stable heating. Avoid rapid fluctuations to support vibrant colouration and overall health.
Aquarium Substrate
A fine gravel or sandy substrate replicates their natural rainforest streambed and enhances their reflective body tones.
Aquarium Decorations
Include driftwood, smooth stones, and natural plants to recreate a rainforest stream environment. Open midwater zones are essential for schooling and natural display behaviours.
