The Mimic Lemon Peel Tang, also known as the Mimic Surgeon, or Chocolate Surgeonfish, has an oval, yellow body while a juvenile. It has blue highlights around the eyes and gill covers, mimicking the Lemonpeel Angelfish (Centropyge flavissimus). (Many of the Acanthurus sp. mimic angelfish.) When mature, the body color darkens towards tan with red highlights forming around the eyes and pectoral fins. The dorsal, anal, and caudal fins take on the hues of green but remain tipped with the tan body color.
A 125 gallon or larger aquarium with large amounts of live rock is necessary to provide both plenty of swimming room, and territories within the live rock. It is aggressive towards other Tangs and Surgeonfish, but is peaceful with other fish.
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. These are great fish for controlling algae in the saltwater fish or reef aquarium.
