Queen Triggerfish - in The Aquarium

In The Aquarium

As one of the largest and most aggressive of the triggerfish, this fish is rarely a good choice as a resident in a marine aquarium. It is however a hardy fish for those who can provide it with a proper environment. Because it grows so large and so quickly the ideal aquarium for this fish is a 500 gallon aquarium. Although some sources argue it can be kept in as little a tank as 125 gallons, when it achieves its adult size of two feet it is unlikely to thrive.

Its diet consists of invertebrates. In aquariums shrimp, squid, clams, octopus, scallops, and crab are all good choices of food.
