Description
The Longhorn Cowfish inhabit the reefs of the Indo-Pacific, usually in the less turbid waters. The body is tan to yellow and covered with white and blue dots, and is occasionally referred to as the Yellow Boxfish; however, the Longhorn is not to be confused with Ostracion cubicus , commonly called the Yellow or Polka Dot Boxfish. In the wild, it is not uncommon to see a 20″ specimen, while in the aquarium the Longhorn Cowfish tends to be dramatically smaller – 16″ or less. When possible, the Longhorn Cowfish should be the first fish introduced in the tank. It is intolerant of other Longhorns, so keep it in a large tank, with some live rock for algae scraping. Use caution if placing the Cowfish Longhorn in a reef tank as it may nibble on tubeworms. When housed correctly, the Cowfish Longhorn is long-lived. Similar to other boxfish, the Cowfish Longhorn’s skin is poisonous and, when threatened, it will release a toxin lethal to other tank members, including other Longhorns. Since they are omnivores, the Longhorn Cowfish should be offered a variety of meaty and vegetable foods. They are slow eaters, and should not be housed with aggressive eaters. Approximate Purchase Size: Small: 1″ to 2″; Medium: 2″ to 3; Large: 3″ to 5″
