Flying Fox

The flying fox (Epalzeorhynchos kalopterus) is a Southeast Asian species of freshwater fish in the family Cyprinidae. It is known to eat green algae. It is sometimes mistakenly referred to as the Siamese algae eater. Very similar in temperament to redtail sharks, Flying Fox's can be territorial and semi-aggressive in planted aquariums, but are compatible with quite a large range of species.

Flying foxes are bottom-dwelling fish native to the fast-flowing foothill rivers and streams of the Thai-Malay Peninsula, Borneo, Java and Sumatra in Southeast Asia. An aquarium with plenty of broad-leaved plants (like Anubias), driftwood and rock for hiding places is recommended.

Do Flying Foxes eat lots of algae?
They eat a fairly moderate amount, but not as much as the Chinese Algae Eaters for which they are commonly confused with. They do not consume beard or red algae.

Are Flying Foxes aggressive?
Flying Fox fish can be aggressive and territorial, but they do not eat other fish or large species of shrimp. They have been known to bully smaller, shy or vulnerable species, so exercise caution when introducing tankmates. Flying foxes are less likely to be aggressive when kept solitary. A group of flying foxes will exhibit territorial behavior.

Water Conditions

Our conditions: pH 7.5, temp 25 °C
Ideal pH: 6.0–7.5
Hardness: 2-12d H
Water flow: fast preferred
Temperature: 23–27 °C

Ease of Care
Moderate. Can grow quite large but at a fairly slow rate. Will prefer fast flowing water, and a softer, sandy substrate. A bit of research will uncover a range of compatible tank mates.

Feed a mixture of algae wafer and greens, like courgette and spinach leaves. As they grow, they will eat dried flake and granules. Ensure the aquarium has a steady source of algae.

The species does not breed readily in home aquaria. Difficult to sex, females tend to be plumper.

Life Span
They can live up to 10 years in perfect conditions.
