Picture By Mike Lavery The African Blockhead is an interesting fish due to its markings and distinctive humped head. The fish forms strong pairs and has plenty of character preffering to stay at the bottom of the aquarium and take residence in caves and other hiding spots. Whilst behaivour varies between individuals, some are territorial and aggressive so only robust, sizeable tankmates are recommended. Otherwise easy to care for and an interesting, robust aquarium fish.
