This beautiful species is virtually indestructible. This species can usually be kept with other groupers, but keep only one Argus Grouper per tank. Although it can be shy when initially introduced to the aquarium, with time it will spend more time in the open, becoming quite bold. Like most groupers, it can eventually be trained to take food from your hand. Like all groupers, it will eat any fish that they can swallow whole and behave aggressively towards tankmates that intrude into its preferred hiding places. It will also eat ornamental shrimps and crabs. Extremely easy to care for.
