Hilda Creek Rainbow – Melanotaenia sp. Hilda Creek
The Hilda Creek Rainbow (Melanotaenia sp. Hilda Creek) is a striking and energetic rainbowfish species native to the Hilda Creek region of northern Australia. Found in clear, slow-moving tropical streams and shallow pools, this species embodies the brilliant diversity of the Melanotaenia genus. With its glimmering body tones of silver-blue and gold, lively schooling behaviour, and peaceful nature, the Hilda Creek Rainbow is a prized choice for aquarists who value both colour and character in their freshwater aquariums.
Features of Hilda Creek Rainbow

The Best Aquarium Size for Hilda Creek Rainbow
A minimum aquarium capacity of 150 litres is recommended for a small group. For optimal colour development and swimming space, a 200-litre tank or larger is ideal. The aquarium should have a length of at least 90 cm to accommodate their energetic swimming patterns and social interactions. Open areas for free movement are essential, balanced with dense planting around the edges for comfort and security.
Tank Mate Compatibility for Hilda Creek Rainbow
This species is peaceful and thrives with other non-aggressive fish of similar size. Ideal tank mates include:
-
Boesemani Rainbowfish
-
Dwarf Neon Rainbowfish

Diet for Hilda Creek Rainbow
In the wild, M. sp. Hilda Creek feeds on small insects, crustaceans, and plant matter. In captivity, offer a varied diet of high-quality flakes, micro pellets, and frozen or live foods such as brine shrimp, bloodworms, and daphnia. Supplementing with spirulina or blanched vegetables enhances colour vibrancy and digestive health. Small, frequent feedings throughout the day promote natural activity and maintain excellent condition.
Aquarium Setup Hilda Creek Rainbow
Aquarium Filtration
Employ an efficient biological and mechanical filtration system to maintain crystal-clear, oxygen-rich water. Moderate water flow helps replicate their natural habitat and supports their active swimming habits.
Aquarium Plants
Incorporate live plants such as Vallisneria, Hygrophila, and Java Fern. Arrange them densely along the back and sides, leaving central open areas for schooling. Floating plants can provide gentle shade and help diffuse bright light.
Aquarium Lighting
Bright, full-spectrum lighting highlights the iridescent scales of the Hilda Creek Rainbow and promotes healthy plant growth. Maintain a consistent lighting schedule of 8–10 hours daily.
Aquarium Heating
Keep the water temperature stable between 24–28°C with a reliable heater and minimal fluctuations. Consistency is crucial for maintaining strong colouration and immune health.
Aquarium Substrate
Use fine gravel or sand to emulate their natural streambeds. A light-coloured substrate enhances the fish’s reflective tones under aquarium lighting.
Aquarium Decorations
Include smooth rocks, driftwood, and natural plants to provide a balanced environment. Leave open swimming zones in the centre of the tank, allowing for natural shoaling and display behaviour typical of healthy rainbowfish.
