When housing, it is best to keep the Brown Heniochus in a 125 gallon tank or larger with live rock for hiding. These fish should be kept with other peaceful fish or fish of the same species.
 
The diet of the Brown Heniochus should include: mysis, frozen shrimp, crab, krill, zooplankton and other invertebrates. It is also necessary to  provide regular vegetable food sources and vitamin-boosting supplements.
