Floodplains	Variable water levels, rich biodiversity	Central Australia, West Papua

Understanding Rainbowfish Behavior: A Social and Peaceful Nature

Rainbowfish species are known for their peaceful temperament and social behaviors, making them ideal for community aquariums. Key behaviors include:

• Schooling: Rainbowfish thrive in groups, where their vibrant colors are displayed to the fullest. A group of six or more is recommended for optimal happiness and health.
• Breeding Rituals: During breeding, males display brighter colors to attract females. Their courtship dances are a spectacle of synchronized movements and color displays.
• Foraging: As omnivores, they forage for both plant matter and small invertebrates. In aquariums, they appreciate a varied diet that includes high-quality flake food, live or frozen daphnia, and brine shrimp.

Rainbowfish in the Aquarium: Bringing the Rainbow Home

For aquarium enthusiasts, Rainbowfish species are a delightful addition, providing a splash of color and dynamic activity. Here is how to care for these aquatic gems:

Setting Up an Ideal Habitat

Creating a suitable environment for Rainbowfish in captivity involves replicating their natural conditions:

• Tank Size: A minimum of 20 gallons is recommended for a small group to allow adequate swimming space.
• Water Parameters: Maintain a temperature of 72-82°F, pH level of 6.5-8.0, and a hardness of 10-20 dGH. Clean, well-oxygenated water is crucial.
• Aquascaping: Incorporate plants like Java fern and Anubias, which provide cover and mimic their natural habitat. Driftwood and rocks can add to the tank's aesthetic appeal.

Colorful Companions: Suitable Tank Mates

Rainbowfish are highly compatible with other peaceful species. Consider the following companions:

• Tetras: Peaceful and similarly small-sized, making them harmonious neighbors.
• Corydoras Catfish: These bottom-dwellers complement Rainbowfish by cleaning the substrate without competing for the same food resources.
• Dwarf Gouramis: Their calm nature and distinct coloration make them an attractive pairing.
