This very interesting and comical fish makes a fine addition to most tanks, although it is not to be trusted in a reef tank with small shrimps. Hawkfish get their common name from the fact that their usual behavior is to perch up on the top of a piece of rock or coral and swoop down on their unsuspecting prey as the bird would do to a mouse or rabbit. Do not be misled by the fact that the mouth is long and pointed – it is also large, and they will, in fact, eat any fish or invert that they can catch.
Feeding the longnosed hawkfish is not a problem, as they will easily become accustomed to eating any meaty foods such as shrimp, clam or mysis shrimps, as well as almost any of the prepared frozen foods. This fish is usually not a problem with other fishes that do not resemble it, but with other hawkfishes, or similarly shaped fish such as gobies and the like, there will often be territorial problems. The hawkfish will almost always win in such a confrontation, and therefore you are best not to include any fish of the same shape in the tank with a hawkfish. Also, they have a reputation for being jumpers, so the tank should be securely covered.
