Flying fox

Introduction

The Flying Fox (Epalzeorhynchos kalopterus) is a popular freshwater fish among aquarists, renowned for its striking appearance and algae-eating habits. With a sleek, elongated body adorned by a bold black stripe running from head to tail, this species adds both beauty and functionality to home aquariums. While often sought after for its algae control capabilities, the Flying Fox requires specific care to thrive, making it suitable for aquarists with some experience.

Care and Environment

Providing optimal care for the Flying Fox involves replicating its natural habitat and meeting its specific needs.

What is the minimum tank size for a Flying Fox?

A single Flying Fox requires a minimum tank size of 113.5 liters (30 gallons) to accommodate its active nature and territorial behavior. For a group, a larger tank of at least 243 liters (64 gallons) is recommended to reduce aggression and provide ample swimming space. (, )

What are the ideal water parameters for a Flying Fox?

Maintain water temperatures between 23°C and 27°C (73°F to 81°F), with a pH range of 6.0 to 7.5, and water hardness between 2 to 12 dGH. Consistent water quality is crucial, as Flying Foxes are sensitive to fluctuations.

How should the tank be set up for a Flying Fox?

Use a fine gravel or sand substrate, and include rocks, driftwood, and broad-leaved plants to create hiding spots and mimic their natural environment. Ensure the tank has a moderate to strong current to replicate the flowing waters of their native habitats.

Lighting should be bright to promote algae growth, which serves as a natural food source. However, supplement their diet with algae wafers, fresh vegetables like spinach and zucchini, and occasional live or frozen foods such as bloodworms and brine shrimp to ensure balanced nutrition.

Be aware that Flying Foxes can become territorial, especially as they mature. Providing ample space and hiding spots can help mitigate aggressive behaviors. Regular water changes and efficient filtration are essential to maintain water quality and support their health.

Origin and Habitat

Native to Southeast Asia, the Flying Fox inhabits fast-flowing rivers and streams across the Thai-Malay Peninsula, Borneo, Java, and Sumatra. These environments are characterized by clear waters with sandy or rocky substrates and abundant vegetation. During the wet season, they may migrate into flooded forest areas, showcasing their adaptability to varying conditions.

Temperament and Compatibility

Flying Foxes are generally peaceful but can exhibit territorial behavior, particularly towards similar-looking species or their own kind. It's advisable to keep them singly or in larger groups to disperse aggression. Suitable tank mates include barbs, danios, tetras, rasboras, gouramis, and angelfish. Avoid housing them with other bottom-dwelling species or similar-looking fish to prevent territorial disputes.

Can Flying Foxes be kept with other algae eaters?

It's best to avoid keeping Flying Foxes with other algae-eating species, as competition for food and territory can lead to aggression.

Do Flying Foxes prefer to be kept alone or in groups?

While they can be kept singly, if housed in groups, ensure the tank is large enough to provide each fish with sufficient territory to reduce aggressive interactions.

Interesting Facts

Despite their reputation as algae eaters, Flying Foxes do not consume red algae, and their effectiveness in controlling algae diminishes as they mature. They are often confused with the Siamese Algae Eater (Crossocheilus siamensis); however, Flying Foxes have a smoother-edged black stripe and more colored fins, whereas Siamese Algae Eaters have a jagged-edged stripe and clearer fins. Breeding Flying Foxes in home aquariums is extremely rare, with most specimens in the trade being wild-caught or farmed using hormone-induced methods.
