A 30 gallon or larger aquarium with plenty of hiding places is acceptable for this hardy and aggressive fish. It should not be kept with larger more aggressive hawkfish. Although it eats small fish and shrimp, with caution, it can make an excellent reef inhabitant.
The Falco Hawkfish diet should include a variety of marine meats, frozen preparations, and live feeder shrimp.
