overviewThe Port Jackson Shark is also known as the Bullhead or Horn Shark, and originates from the intertidal waters of Australia. These sharks have a spine at the front of both dorsal fins that can cause injury. Their body is an olive green color with darker green or black irregular markings. These sharks can be difficult to acclimate to aquarium life, but prove to be extremely hardy thereafter.
It is a difficult fish to acclimate and may not eat. 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.
