Black Banded Cat Shark
Known as a Cat Shark because the barbels at the mouth resemble cat whiskers, this species is also called the Brownbanded Bamboo Shark. It features a cream-colored body with broad dark black stripes. Larger individuals may display large, muted brown spots between the stripes.
This bottom-dwelling shark is commonly kept in home aquariums. It feeds on any available crustaceans and grows to a relatively small size. However, it requires a minimum of a 360-gallon tank as an adult.
It needs sand as a substrate because its abdomen is sensitive and can be scratched by coarse materials, which may lead to infection. Copper-based medications should never be used with this species.
Feeding can be challenging when the shark is first introduced to the tank.

The Black Banded Cat Shark is a unique and calm addition to my tank. I’ve had it for six months and it’s active on the bottom without causing any stress to other fish. I use sand substrate and avoid copper treatments. Feeding took some time to adjust, but now it eats frozen shrimp regularly.

It’s a beautiful fish with a distinctive appearance. I made sure to get a large tank and use sand. It’s not aggressive and stays near the bottom. The only challenge was the initial feeding, which required patience and offering small crustaceans.

After reading the care notes, I was confident in keeping this shark. It’s peaceful and doesn’t compete with other species. The black and cream stripes are striking. I’ve maintained a 400-gallon tank with sand substrate and no copper products.
