Overview

The Convict Tang, also known as the Convict Surgeonfish, has a stunning white to silver body highlighted by six vertical black bars. The peduncle spines (near the tail) are rather small compared to that of other Tangs. A great addition to the reef or fish only aquarium.

It requires a large area in which to swim - at least a 125 gallon aquarium. It should not be included in a tank with other species of Tangs, since they will harass it. It will live peacefully with other Convict Tangs if all are introduced to the tank at the same time.

Convict Tangs have no distinguishing characteristics which will help differentiate males from females. They are very difficult to breed in the aquarium setting because the fry remain in the planktonic stage for months, and are in constant danger from filters.

Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.

Customer Testimonials

T.J. Lock Streator , IL
Great fish to add to a community tank. Took a day to adjust but then started his grazing and hasn't stopped. Not a lot of color, but makes up for it with personality. Loves the seaweed clip and Omega Brine. Was introduced to a Blue Angel juvenile and instantly became buddies. Doesn't bother any of the smaller fish. I love my not so bright fish!
