Danio aesculapii, known as the Aesculapius Danio, is a vibrant and active species, ideal for well-planted community aquariums.
Overview
Danio aesculapii, commonly known as the Aesculapius Danio, is a colorful and lively freshwater fish native to the rivers of Southeast Asia. This species is appreciated for its vibrant appearance, characterized by its striking vertical stripes and active nature. It is an excellent addition to community tanks and does well in groups.
Tank Requirements
Danio aesculapii requires a tank of at least 50 liters. They prefer a water temperature between 22-28°C, with a pH range of 6.0-7.5 and a general hardness (dGH) of 5-12. Providing a well-planted tank with plenty of open swimming space is important, as these fish are very active. Moderate water flow and a good filtration system will help maintain their health and vibrant coloration.
Feeding and Diet
In the wild, Danio aesculapii feeds on small insects and aquatic invertebrates. In an aquarium setting, they are omnivorous and can be fed a varied diet including high-quality flakes, micro pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. A balanced diet supports their health and enhances their colors.
Care and Maintenance
Danio aesculapii is relatively easy to care for, making it suitable for both beginner and experienced aquarists. Regular water changes and monitoring of water quality are essential to keep these fish healthy. Due to their active nature, a well-maintained tank with stable water conditions is crucial for their well-being.
Compatibility
Aesculapius Danios are peaceful fish that can be kept with other non-aggressive species. Ideal tank mates include small tetras, rasboras, and other danios. They should be kept in groups of at least 6 to reduce stress and encourage natural schooling behavior.
Breeding
Breeding Danio aesculapii in captivity is achievable with proper conditions. They are egg scatterers, so providing a breeding tank with fine-leaved plants will help increase the chances of successful spawning. After spawning, remove the adults to protect the eggs. The eggs typically hatch within 2-3 days, and the fry can be fed with infusoria or liquid fry food.
