Like all cichlids, Males will have the most color, while most females with will lack the color of the males. To have the most coloration you want to order a dominant male.
The OB Red Blotch Zebra is a member of the Mbuna family of cichlids. They can have an aggressive temperament and should only be placed with other Mbuna. We recommend placing them with something like the Yellow Lab or the Electric Blue Maingano.
