Types of ArowanasThere are several species of arowana, originating from South America, Africa, Australia and Asia.
Asian arowanas tend to be the most highly prized, but they are an endangered species and it is illegal to trade them in unless they are over thirty years old or captive bred (in which case they are marked with microchips).
- Silver Arowanas - These are the most common choice for aquarium hobbyists, but they are also the largest, sometimes growing to four feet in length.
- Black Arowanas -Almost identical to silver arowanas but for their colour, these fish are slightly less hardy.
- Australian Arowanas -These look very similar to their Asian equivalents but are far less expensive. Pearl and spotted varieties are available.
- African Arowanas -A distinctly different shape from other species, these fish are available in a variety of subtly blended colours.
Feeding and CareAll arowanas are carnivorous and strongly prefer live food.
For best results they should be provided with a highly varied diet. Shrimp, prawns, mealworms, crickets, centipedes, krill and frogs are all suitable foods, though any sharp pieces should first be removed and live animals should be quarantined first to avoid the introduction of parasites.
Arowanas enjoy eating smaller fish but should not be fed these too often, as a build-up of fat in their bodies can lead to health problems. Many arowanas will take pellet food, but this is not sufficient on a daily basis.
Individual preferences vary, so be ready to experiment to see what your arowanas like.
