Behavior
One of the hardiest and most peaceful tangs available. Naturally schooling in the wild, Convict Tangs adapt well to aquarium life and are rarely aggressive. A great choice for community reef tanks. Their bold pattern and constant activity make them highly entertaining.
Diet & Feeding
Herbivore. Primarily grazes on turf algae. Offer dried seaweed daily on a feeding clip and supplement with spirulina, marine algae-based pellets, and frozen herbivore preparations.
