Epalzeorhynchos kalopterus

Epalzeorhynchos kalopterus, commonly known as the Flying Fox, is a sleek and fast-moving fish known for its role in controlling algae in the aquarium.

Overview

Epalzeorhynchos kalopterus, also known as the Flying Fox, is a highly active and sleek fish commonly found in fast-moving streams and rivers in Southeast Asia. Growing to around 12-15 cm, it is recognized for its role in controlling algae in aquariums. Its body is streamlined with a striking black horizontal stripe running from the nose to the tail, bordered by gold and brown.

Tank Requirements

The Flying Fox thrives in a tank of at least 120 liters, with water temperatures between 24-28°C. The ideal pH range is 6.0-7.5, and the general hardness (GH) should be between 5-12. It prefers a well-oxygenated tank with moderate water flow and plenty of hiding spots, such as rocks and driftwood, to mimic its natural environment.

Feeding and Diet

In the wild, Epalzeorhynchos kalopterus grazes on algae, plant matter, and small invertebrates. In an aquarium, it should be provided with a balanced diet that includes algae wafers, spirulina-based foods, and occasional live or frozen foods like bloodworms and daphnia. Providing a varied diet helps maintain its vibrant colors and energy.

Care and Maintenance

The Flying Fox is relatively hardy, but it requires clean water to stay healthy. Weekly water changes of 20-30% are recommended. Regularly monitor the water quality, as poor conditions can lead to health issues. Ensuring proper filtration and water flow is essential for the well-being of this species, as it prefers well-oxygenated water.

Compatibility

While generally peaceful, the Flying Fox can become territorial with other similar-shaped fish, especially as it matures. It is best kept with fast-moving, non-aggressive species such as tetras, barbs, and rasboras. Avoid housing it with slow or long-finned species, as it may harass them. It is also important to provide plenty of hiding spaces to minimize territorial aggression.

Breeding

Breeding Epalzeorhynchos kalopterus in captivity is considered very difficult. Little is known about their breeding habits in aquariums, and most Flying Foxes available in the trade are wild-caught. If breeding is attempted, a large tank with slightly warmer water (26-28°C) and soft, acidic water may be needed to simulate breeding conditions, though success rates are typically low.
