Thinking of recreating a mini sea world at your home? It is known that hawkfishes are excellent as aquarium fish. However, before heading for the purchase be sure to know these crucial facts. Firstly, the minimum tank size must be 30 gal (136 l). Secondly, a pH of 8.1-8.4 has to be maintained along with a suitable water temperature. Marine saltwater fishes fail to adapt in a freshwater aquarium which implies that freshwater fishes such as goldfish and rainbow fish must not be kept together. Tank fishes must be compatible and hawkfishes go well with fishes like skate fish, hogfish, or corkwing wrasse. Corals can be added to the tank but with caution. Hawkfishes prey on small fish, crustaceans like shrimp, and plankton meaning one needs to be extra cautious of picking tankmates.
