Neon Rainbow - Melanotaenia praecox

The Neon Rainbowfish (Melanotaenia praecox) comes from the small, lush jungle streams in Western New Guinea (formerly Irian Jaya), the Mamberamo region of West Papua. They feed on vegetation, insects, small worms and fish eggs. This fish is classic omnivore, it is very easy to keep. This fish is one of the best choices for the community tanks.

Ideal Tank Mates

Neon Blue Rainbowfish thrive in groups of 10 or more with peaceful, similar-sized fish. For example, tetras, rasboras, or other rainbowfish pair well. However, avoid large or aggressive species to prevent stress. Since they are active schoolers, a 60-litre tank or larger suits them best. Additionally, dense plants and open space enhance their vibrant colors and harmony.

Feeding & Nutrition

Neon Blue Rainbowfish eagerly consume an omnivorous diet. In the wild, they feed on insects, worms, and plants. Therefore, offer high-quality flakes, supplemented with frozen foods like bloodworms. Importantly, include plant-based foods and feed 2-3 times daily, within 5 minutes. This approach maintains their radiant colors and ensures robust health in your aquarium.
