Dimidiochromis dimidiatus

Dimidiochromis dimidiatus shares the extreme lateral compression of its congener D. compressiceps but differs in patterning and behavior. The 'dimidiatus' name refers to the divided coloration — males develop a blue-silver anterior half and a distinctly darker, almost black posterior half, creating a striking bisected appearance. This is a thinner, more elegant-looking fish than the Eye-biter and somewhat less aggressive.

In the wild, dimidiatus is associated with vegetated shores and papyrus margins where it hunts smaller fish. In the aquarium it appreciates some visual cover from tall artificial plants or rocky overhangs, which mimic its natural habitat. It is less of a dedicated eye-biter than compressiceps, functioning more as a generalist laterally compressed predator.

A maternal mouthbrooder producing moderate broods. Less commonly available in the trade than D. compressiceps, making it a desirable find for the Malawi Hap collector. Best kept with fish that are too large or too different in body shape to be targeted.
