Danio kerri, also known as Blue Danio, is a peaceful, vibrant species well-suited for community tanks, thriving in schools.
Overview
Danio kerri, commonly known as Blue Danio, is a vibrant freshwater fish originating from Southeast Asia. Its striking blue and purple hues make it an eye-catching addition to any community aquarium. Like other danios, Danio kerri is an active schooling fish that enjoys being in groups.
Tank Requirements
Danio kerri requires a minimum tank size of 50 liters. The ideal water temperature is between 22-26°C, with a pH level of 6.0-7.5 and water hardness of 5-15 dGH. These fish prefer a planted tank with ample open swimming space and a gentle current to replicate their natural habitat.
Feeding and Diet
In the wild, Blue Danios feed on small insects, larvae, and plankton. In the aquarium, they are omnivorous and will accept a wide variety of foods, including high-quality flake food, pellets, and live or frozen foods such as brine shrimp and daphnia. A varied diet helps maintain their vibrant colors and overall health.
Care and Maintenance
Danio kerri is relatively easy to care for, making them suitable for beginner aquarists. Regular water changes, efficient filtration, and good water movement are essential to keeping these active fish healthy. Monitor water parameters to ensure stable conditions, and watch for signs of stress or illness.
Compatibility
Blue Danios are peaceful fish that do well in community tanks with other non-aggressive species. Good tank mates include small tetras, rasboras, and corydoras. They should be kept in schools of at least 6 to reduce stress and encourage natural schooling behavior.
Breeding
Breeding Danio kerri in captivity is achievable but requires careful attention. These fish are egg scatterers, and a well-planted breeding tank will increase the chances of successful breeding. Remove the adults after spawning to protect the eggs. The fry will hatch in 2-3 days and should be fed infusoria or powdered fry food until they are large enough to accept larger food.
