Notes: The Horn Shark is also known as the Bullhead Shark. It has a spine at the front of the dorsal fin that can cause injury. It may have a series of small spots marking the body.
It is a difficult fish to acclimate and may not eat. The best way to encourage the Horn Shark to eat is by offering small pieces of cleaned squid or fresh water ghost shrimp. The squid has a strong odor and helps to entice its appetite.

When first introduced into the aquarium, small pieces of cleaned squid or live saltwater feeder shrimp should be used to entice this fish to eat. Then it may be fed shrimp, scallops or pieces of fresh marine fish. Once eating well, it will eat virtually any crustacean or mollusk in the aquarium. It is a nocturnal feeder, and will also prey upon any sleeping fish small enough for it to eat whole.

It requires sand as the substrate since its abdomen is easily scratched by a coarser substrate and that could result in an infection. It should never be exposed to copper based medications.

Evanish: The tank size is acually correct. 500 Gallons is the recommended size, but 280 is fine for a horn shark. Adults should be in a 400 gallon tank, though.
