Physical Appearance

The body of the Giant Whiptail catfish features a camouflage pattern of different shades of brown, often ranging from very dark brown to very light brown. It can usually grow up to 7.5 inches, which is a fairly large size, but there are Giant Whiptails that grow to just under 10 inches depending on how much they are taken care of. Its slender and elongated body may not be as peculiar as you might expect, but what gives it its exotic look is its dorsal fin that is tall and large. Its fins are also covered by a camouflage pattern, increasing its chances of disappearing into the background in a driftwood environment.

Behavior and Temperament

The Giant Whiptail is nocturnal, which means you can expect to see it most active at night or when it starts to get dark. It loves hiding and resting on driftwood, so make sure there is plenty of that in your tank. It usually stays near the bottom of the fish tank because it would be easy to feed on algae and hide down there. Generally, this catfish is peaceful and will not bother other types of fish inside the fish tank. However, it may be easy target for larger and more aggressive fish so make sure you don't put it in a fish tank with those kinds of fish. Keep their numbers low, especially if you have a small tank because Giant Whiptails can become extremely territorial with their own kind.


The Giant Whiptail mainly feeds on algae and other types of aquarium plants, including small pieces of zucchini and cucumber. Wafers based on vegetables are also appropriate food for this catfish. You can also feed it meat like brine shrimp and bloodworms, both of which could be frozen or live. You should keep this fish in a freshwater fish tank with a temperature of 22 degrees to 28 degrees Celsius and a pH level of 6.5 to 7.5. The fish tank should have a minimum size of around 50 gallons to give this catfish enough room to swim around in. It is fairly sensitive to the water conditions of a fish tank so regular water changes should be implemented to keep it healthy and happy. Remember to provide an environment where algae can grow to keep the Giant Whiptail catfish properly fed.
