Size / Weight / umur
Maturity: Lm ? range ? - ? cm
Max length : 13.0 cm SL jantan/; (Ref. 4967)
Duri punggung (Keseluruhan (total)): 16 - 19; duri punggung lunak (Keseluruhan (total)): 8-10; Duri dubur 3-4; Sirip dubur lunak: 8 - 10. 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).

This species is a mouth-brooder (Ref. 126033). Nothing has been reported about its breeding period, but most probably it reproduces at the start of the short dry season from December to January (Ref. 126033).
