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).
雜食性, 沼澤-居民。 在湖中, 它是發現只有在河口與在他們的相連沼澤中.(參考文獻 6770)
