Care Guide

Diet

Synodontis petricola is an omnivore that readily accepts a wide variety of foods including high-quality sinking pellets, algae wafers, and frozen or live foods such as bloodworms, brine shrimp, and daphnia. Feed once or twice daily, offering only what can be consumed within a few minutes. Supplement with vegetable matter occasionally to ensure a balanced diet.

Behavior

Petricola Catfish are social, active fish that do best when kept in groups of three or more, becoming more confident and visible in larger numbers. They are primarily nocturnal but will often venture out during the day, especially when comfortable in their environment. They enjoy rocky caves and crevices for shelter and will occasionally display cuckoo-like brood parasitism behavior when spawning alongside mouthbrooding cichlids.

Breeding

Breeding Synodontis petricola in captivity is possible but challenging; they are brood parasites that deposit their eggs among spawning mouthbrooding cichlids, whose host then incubates the catfish eggs alongside their own. To encourage spawning, condition the fish with varied live and frozen foods and provide suitable cichlid tankmates as hosts. The catfish fry hatch quickly and may consume the host's eggs, making controlled breeding setups necessary for success.

Common Diseases

Ich (White Spot Disease)

Symptoms

Small white spots resembling grains of salt on the body and fins, flashing against surfaces, lethargy

Treatment

Raise water temperature gradually to 28-29 C, treat with ich-specific medication; use half doses as catfish can be sensitive to medications

Bacterial Infection

Symptoms

Red sores, ulcers, frayed fins, lethargy, loss of appetite

Treatment

Improve water quality, perform frequent water changes, treat with antibacterial medication appropriate for catfish at reduced doses

Bloat (Malawi Bloat)

Symptoms

Swollen abdomen, loss of appetite, rapid breathing, lethargy

Treatment

Improve diet variety, ensure high water quality, treat with metronidazole if bacterial or parasitic cause is suspected

Skin Flukes (Gyrodactylus)

Symptoms

Excessive mucus, scratching against surfaces, reddened skin, clamped fins
