A terrific and unusual looking shark. The Port Jackson is pretty rare in the aquarium trade and it should be. Although fairly hardy and peaceful, this one just gets to large for the home aquarium. Juvenniles are more brown and coloration which turns into grey as they mature. They also have sharp spines, said to be venomous, at the front of each dorsal fine. These eventually dull with age. |

The Port Jackson Shark (Heterodontus portusjacksoni
) belongs to the family named Heterodontidae. Typically reaching a max size of about 62.9 inches in length, the Port Jackson Shark is generally passive in nature and moderately hardy in stamina. It's more active during the daytime and less at night, and will hang out or do best in the lower tank area. According to FishDB current data, captive breeding success is unreported and there are no external signs of sexual differences. Heterodontus portusjacksoni
should not be housed in a tank less than 500 gallons in size. Tank parameters should be maintained with ph level between 8.1 - 8.3, temperature between 77 - 79 degrees fahrenheit, and a salinity between 1.020 - 1.023. Some of the environmental concerns that you should strive to replicate in your home aquaria to promote succesful acclimation include extra swimming area, extra substrate area, and a stable cave/sheltering ledge.
