The boxfishes are a family, Ostraciidae, of squared, bony fish belonging to the order Tetraodontiformes, closely related to the pufferfishes and filefishes. They come in a variety of different colors, and are notable for the hexagonal or "honeycomb" patterns in their skin and skeletons. They swim in a rowing manner. Fish in the family are known variously as boxfishes, cofferfishes, cowfishes and trunkfishes.

Boxfishes occupy the Atlantic, Indian, and Pacific oceans, generally at middle latitudes, although the common or buffalo trunkfish (Lactophrys trigonus) which lives mainly in Florida waters may be found as far north as Cape Cod. The cowfish variety Lactophrys quadricornis can grow to 30 cm or more in size, but are generally smaller at higher latitudes.

The hexagonal plate-like scales of these fish are fused together into a solid, triangular, box-like carapace, from which the fins and tail protrude. Young boxfishes have a more rounded in shape and may exhibit bright colors. Because of their body scale structure, boxfishes are limited to slow movements.

Boxfish are edible, and are sometimes baked in their own shells.

[edit] In the aquarium

Boxfish generally are very personable fish yet are poorly suited for the home aquaria. They are not thought of as an ordinary aquarium tank mate, but are quickly gaining popularity. They do pose a hazard in the community tank however. They are capable of releasing a very powerful toxin which can kill other fish and in some cases, the boxfish itself. They generally only use it when threatened or dying, but can become disturbed easily with aggressive tank mates or overcrowded aquarium. Generally boxfish are not reef safe.
