Inhabit springs and creeks near the southern and south-eastern shores of Lake Natron. It co-occurs with O. alcalicus and O. latilabris. Observed to nibble at stones and gravel, probably taking mainly algae for food. Omnivorous, taking insects from the water surface as well (Ref. 32272). Females are mouthbrooders (Ref. 32272).
