About the Petricola Catfish
The Petricola Catfish is a beautiful African catfish native to the rocky shores of Lake Tanganyika. Loved for its striking black body covered in crisp white spots, this active bottom-dweller is one of the smallest and most peaceful members of the Synodontis family, making it an excellent choice for both African cichlid and larger community aquariums.
Unlike many nocturnal catfish, Petricola Catfish are often active throughout the day, constantly exploring caves, rockwork, and crevices in search of food. Their inquisitive nature and attractive spotted pattern make them a favourite amongst aquarists keeping Tanganyikan cichlids.
Petricolas thrive in aquariums with rocky caves, strong filtration, and excellent water quality. They are happiest when kept in small groups of three or more, where they display natural social behaviour. They readily accept sinking carnivore pellets, algae wafers, frozen bloodworms, brine shrimp, mysis shrimp, and other meaty foods.
Hardy, peaceful, and full of personality, the Petricola Catfish is one of the best catfish species for African cichlid aquariums.

Common Mistakes
Keeping them alone
Petricola Catfish are naturally social and thrive when kept in small groups.
Not providing enough caves
Rock piles and caves provide security and encourage natural behaviour.
Keeping them in soft, acidic water
As Lake Tanganyika natives, they require hard, alkaline water to remain healthy.
Feeding only algae wafers
Although they will eat algae-based foods, they require a balanced omnivorous diet with plenty of protein.
Poor oxygenation
Excellent filtration and strong water movement help replicate their natural environment and keep them healthy.
