Arowanas are primarily carnivorous (meat eaters) and are known to have large appetites. They will eat crickets, mealworms, earthworms, and krill. You may feed guppies or beef heart as occasional treats


Predatory to smaller fish, can be intolerant of those of same kind unless kept in large schools (in very large tanks).

Tank Environment

Minimum of 150 gallons for a single adult arowana.

pH Range: 6.0 to 7.4, they are quite tolerant of this range as long as the pH is stable.
Temperature: 74 to 80 degrees Fahrenheit 

Provide lots of open swimming space, large wood will hinder movement or cause physical damage. Lots of artificial plants will provide cover and security and will not harm the fish. Keep a tight fitting canopy on the tank as these fish are strong jumpers and can dislodge a flimsy hood. Remove un-eaten food to avoid water fouling.

Tank Mates

Best kept as a single display species, however they will tolerate bottom dwellers and freshwater stingrays, only if the tank habitat is suitable for them.
