Helmet Cowfish EXPERT ONLY

Referred to by many names, including Camel Cowfish, Thornback, Thornbacked Boxfish, Helmet Cowfish, and Hovercraft Boxfish, the Helmet Cowfish requires the care of an experienced aquarist. The Helmet Cowfish has a rather drab, pale tan body with random blotches of blue and occasional black dots. The eyes are large and blue.

The Helmet Cowfish should have a minimum of a 180 gallon tank. Use caution if placing it in a reef tank as it will often nibble at tubeworms. When stressed, the Helmet Cowfish releases a poisonous substance, called ostracitoxin, from its mucous glands which will kill other fish in the tank very quickly.

Very little success has been achieved in breeding this fish in the aquarium setting.

When introduced into a tank, the Helmet Cowfish can be fed a diet of live brine shrimp or bloodworms. After acclimatization, chopped squid, clams, mussels, and herbivore preparations can be fed. This fish has the peculiar habit of coming to the surface and spitting when it is hungry.
