Clown Knif fish
Chitala Chitala
The Clown Knife fish is a member of the Apteronotidae family and the speckled knife fish group. It is considered a true bony fish. When properly cared for, the Clown Knife fish can reach up to one metre in length. It possesses a weak electrical organ at the caudal peduncles which is used to locate food.
It requires a minimum of a 200 litre tank with excellent filtration. It is generally timid and reclusive, preferring a fine-gravel-bottom aquarium with plenty of roots and rocks for hiding places, as well as subdued to dark lighting. To better appreciate this fish, many hobbyists will purchase a "ghost tube," a clear plastic tube that facilitates viewing during the day. Once accustomed to its surroundings, the Clown Knife fish can become incredibly tame and trusting to the point of being hand-held. It does well with other, larger species of a peaceful nature, but may be aggressive towards those of similar or smaller size.
Omnivorous, the Clown Knife fish will eat all types of live foods including meat, chopped earthworms, as well as frozen and flaked foods.
