The Longhorn Boxfish has a peaceful temperament, but it does startle easily and if stressed can release ostracitoxin which is contained in its’ skin. It is capable of poisoning an aquarium, killing everything in it.

The male and female Longhorn Boxfish have a pale, yellow body colour, covered with whitish or bluish spots. There are 2 small horns on the top of its’ head, and at the rear of its’ body. Life expectancy is around 8 years.

Reproduction involves a paired courtship around sunset. In the wild, a male will have several females within its’ territory. Eggs are released by the female and stay in the water table until they hatch and develop into juvenile boxfish.

Despite their peaceful temperament, the Longhorn Boxfish can be aggressive on occasion, but this is not consistent behaviour. It is preferable to add the boxfish to an aquarium first and watch new arrivals, especially other Longhorn Boxfish.

In their natural habitat, Longhorn Boxfish are timid and will hide in corals or weeds if they encounter anything strange in the water (for instance divers). If there is nowhere to hide they may lay motionless on the floor. When the situation becomes too stressful they will start to develop black patches on their skin.

The Longhorn Boxfish can be found on the East African coast and the Red Sea, across to Indonesia and further East towards Japan.

Tank Recommendations for the Longhorn Boxfish

A tank of at least 250 gallons (946 litres) is recommended.

Longhorn Boxfish are curious fish, but slow movers who do not like strong currents. They should be housed in a large tank with plenty of places to hide or shelter. If they are introduced to a reef tank, they will eat small invertebrates.

It is advised not to release any bag water into the tank when introducing a Longhorn Boxfish. If it is removed from the tank during a water change it needs to be kept alone in a separate container.

Suitable Tank Buddies

Longhorn Boxfish have a peaceful temperament and are best suited with fish who have similar behaviour. Aggressive feeders may disrupt its’ eating habits.

The fact that they are capable of poisoning the aquarium means that extra care needs to be taken about their environment and tank buddies to make sure they aren’t harassed or stressed.

There is a possibility in a reef environment that certain corals will be nibbled, and smaller invertebrates are at risk of being eaten.
