overview
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 2-1/4"; Medium: 2-1/4" to 3; Large: 3" to 4-3/4"


Caution: This species secretes or releases toxins when stressed or injured that may kill fish in the aquarium. LiveAquaria.com cannot accept responsibility for any loss that may occur should this animal poison the aquarium.

Please note: We guarantee that ALL aquaria species we offer will arrive alive and in good condition. However, because of the increased level of care required for this particular species, it has been designated as "Expert Only." This species is recommended only for the expert aquarist, zoo, or research institution please.
