In its natural habitat, the Mimic Half Black Tang is constantly on the move in search for filamentous algae. A 125 gallon or larger aquarium with plenty of water movement, large amounts of live rock, ample swimming room, and territories within the live rock is necessary.
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 Seaweed Selects are all ideal products and are very easy to use. These are great fish for controlling algae in the saltwater fish or reef aquarium.
