Mimic Tang – Half Black is widely distributed in the Indo-West Pacific, found from coastal areas to outer reef crests. Juveniles often mimic other pygmy angelfish species in color and shape.

As the fish grows beyond the size of the model, its tail transitions from rounded to lunate, and its color shifts to match the adult form. Maximum length reaches 20 cm.

Easy to care for and very active in the tank. The fish shows interesting color changes as it grows. Algae wafers work well for feeding. Great for a beginner marine setup.

The juvenile stage looks like a small angelfish, which is fascinating. After a few months, it started changing tail shape and color. Feeding is simple with daily algae-based food.

Perfect for a reef tank. It doesn’t stress other fish and stays calm. The color shift when it grows is noticeable and beautiful. Very happy with the purchase.
