There are six known species of Arowanas, and all of them can grow to be more 36" long. So these are fish for very large aquariums. Arowanas are often called Dragon Fish or Arrowanas.

Appropriate Home
Eventually a very large aquarium with an exterior power filter with a BIO-Wheel, and a maximum of 1/4 inch of gravel. The water temperature should be between 75 and 80 degrees F. Click here for general information about warm water aquariums.

Recommended Diet
When they are small, Arowanas should be fed live and frozen brine shrimp, black worms, and a few small fish. My friend Fred used to keep his Arowanas in an aquarium with hundreds of small White Clouds. I could see the Arowanas usually did well, but I wondered how many White Clouds were eaten by the small Arowanas.

As Arowanas grow larger they are usually fed larger fish. Silver Arowanas have been seen leaping out of the water to eat insects from trees. African Arowanas will survive and grow on the diet given above, but this fish is also a filter-feeder, and feeding filter-feeding fish in aquariums is usually very difficult.

Compatibility
We keep Arowanas in our aquariums for only a few weeks, until they were acclimated and ready to be shipped to our customers. So we don't have much first hand experience about compatible tank mates for Arowanas. Arowanas are often seen in large aquariums with large Plecostomus Catfish, large active Cichlids, large Catfish, and large Tinfoil Barbs.

Size and Life Span
All the various species of Arowanas can grow to be be very large. The maximum known sizes are given in the table above. Their life spans are unknown to us, but all Arowana species probably live for many years.
