Diagnosis: Astatoreochromis straeleni can be distinguished from A. alluaudi by the possession of 3-4 anal spines vs. 4-7; 16-18, exceptionally 19, dorsal spines vs. 17-19 dorsal spines, rarely 16 or 20 (Ref. 126033).
Aastatoreochromis straeleni is primarily a riverine species, prefering clear water and caught in swampy flooded areas and marginal vegetation with a high water transparency (Ref. 126033). In Lake Tanganyika, it is found only at the mouths of rivers and in their associated swamps (Ref. 6770). Omnivorous, swamp-dweller (Ref. 6770), reported to feed mainly on snails, ostracods and insects (Ref. 126033). This species is a mouth-brooder (Ref. 126033).
