But these fish can adapt to most types of water, and so as usual it's best not to try to change the pH or hardness.

Aquarium Size: Eye-Biter Compressiceps Haps will eventually need to live in an aquarium with at least 80-gallons of water. But a bigger aquarium is better.

Popularity: Since maybe the 1980s the Eye-Biter Compressiceps Hap from Lake Malawi has been a popular aquarium fish.
Names: Their scientific name is Dimidiochromis compressiceps.
Variations: Like a lot of aquarium fish, there is an albino variation of this fish.
Malawi is a huge lake, and these Eye-Biters are found over a wide area
of the lake, so there we think it's likely that there may be other
variations, but we do not yet know about them.
There are now other species in the genus Dimidiochromis.
