from Scot W Michaels' book "Marine Fishes":
"An excellent aquarium fish, relatively peaceful and quite handsome when well fed and properly illuminated. Usually not hostile to tankmates, it tends to be shy at first, becoming bolder with time. More than one can be kept per tank if they are added simultaneously as juveniles in a large tank. Should be provided with a piece of rock with a hole where it can retreat if threatened. It may bite: before handling aquarium decorations to clean or relocate them, make sure you know where your triggerfish is."
