features

Astatoreochromis species are 12 to 19 cm long, females remain slightly smaller. Their body is of the typical perch shape and somewhat flattened on the sides. The head is big and beefy. The enlarged teeth in the outer rows of teeth are characteristic of the genus. They are conical and two-pointed. Behind the first row of teeth there are one or two more. The pharyngealia are covered with molar-like teeth. The pelvic fins have elongated outer fin rays , the caudal fin rounded. The dorsal fin of the animals is supported by 15 to 16 fin rays. The number of spines in the anal fin is four (rarely three) to six. Astatoreochromis species inhabit the papyrus swamps on the edge of the great lakes and rivers. All are omnivores and mouthbrooders . On the anal fin they have 6 to 20 egg spots , which are arranged in 3 to 4 rows.
