Appearance and identification
S. petricola usually has a white dorsal leading edge and darker lower fins. S. grandiops is a synonym, so the old name does not add another species.
Aquarium environment
Retain sheltered lower routes and use plants suited to alkaline water. Planting does not prevent predation or brood parasitism.
Diet and feeding
Feed complete sinking foods and suitable frozen foods. It eats snails but is not a cleaning fish.
Same-species behaviour
Provide stable alkaline water, clean conditions and several shelters. Keep four or more.
Compatibility limits
Small fish may be swallowed. Eggs can enter a mouthbrooding cichlid's brood and the catfish larvae consume host eggs or fry; this matters when raising cichlid young.
