Keep only together with other big fishes.
Needs very much place for swimming; if it is not enough, it may become aggressive.
Be careful, if you also keep small shrimps!
Can be kept in groups as long as they are juvenile, but should be separated, up to 2 fishes, once grown. Don't sleep in the sand like Haliocheres, but in a hiding-place in the rocks.
