Hawkfish

Hawkfish belong to the Cirrhitidae family. The genera of Hawkfish available in the aquarium trade consist of Cirrhitus, Oxycirrhitus, Neocirrhitus, Paracirrhites, and Amblycirrhites. Hawkfish are found in tropical waters throughout the world, and are almost always associated with coral reefs. Most Hawkfish reach a size of three inches in an aquarium, and the largest member of the family reaches an adult size of over 20 inches in the wild. Hawkfish are closely related to Morwongs. Most Hawkfish have cirri, or hairs on the tips of their dorsal (top) fins, and also behind their nostrils.

Hawkfish get their name from their hunting techniques, which are similar to a hawk. The fish will rest atop the highest point on the coral reef, waiting for suitable prey to appear. The fish will then dive down to capture prey. They consume plankton, crustaceans, and small fish in the wild.

Hawkfish are hardy aquarium specimens that adjust well to life in an aquarium. Hawkfish can do well in reef aquariums, although they will eat smaller shrimp and fish. A well-sealed lid and adequate hiding places are required to maintain these fish in an aquarium. In most cases, only one Hawkfish can be kept per tank, unless the aquarium is extremely large.

These fish are found in small harems or in pairs. No distinguishing characteristics differentiate males from females, and the breeding of these fish in an aquarium is extremely difficult.

They are generally compatible with: Dwarf Angelfish, Large Angelfish, Anthias, Basslets, Batfish, Blennies, Boxfish, Butterflyfish, Cardinalfish, Clownfish, Damselfish, Filefish, Goatfish, Gobies, Hawkfish, Hogfish, Parrotfish, Pseudochromis, Puffers, Squirrelfish and Tangs & Surgeons.

Caution is required with: Anglers & Frogfish, Grunts & Sweetlips, Triggerfish and Wrasse.

They are not compatible with: Eels, Groupers, Lionfish & Scorpionfish, Seahorses & Pipefish and Sharks & Rays.
