Arowana: Ideal Habitat & Diet

Q: I’m new to fish-keeping and recently bought one arowana and some basic necessities from a local fish shop. Basically, I would like to know what type of tank, diet, and habitat are suitable for arowanas? Is a 2ft tank, a filter running on an air pump supply, and a diet of small frogs sufficient for now? What other things I need to know on maintaining my new pet fish in good condition.

Usually I advise new hobbyists to do thorough research before acquiring the necessary aquarium equipment and finally getting the fish. In your case, you did the backward procedure. We will then make do what you have got right now.

Arowanas in their natural habitat feed on smaller fish and frogs, as well as insects that have dropped into the water or resting near water surface. However, small frogs can easily dirty the water. Hence a good filtration system is vital. More tips on how to maintain a proper filtration system here.

I would highly suggest you vary their diet instead of just frogs alone. Live food such as small frogs and fish are nutritious, but sometimes carry disease. Nowadays, there is commercial pellet food specially for arowanas. These offer nutritious value close to that of live food and are safer as they don’t introduce unwanted diseases.

Arowanas can grow easily up to 24inches. You have to consider their potential sizes when planning their housing. A 2ft tank is too small to rear an arowana to adulthood. Get a tank that’s at least four feet and a suitable corner or canister filter recommended for that size.
