Chocolate Surgeonfish, displays a yellow body with blue accents around its eyes and gill covers as a juvenile, resembling the Lemonpeel Angelfish. As the fish matures, its body color shifts to tan with red highlights forming around the eyes and pectoral fins. Its dorsal, anal, and caudal fins become green-hued but still feature the tan body color on their tips. To provide ample swimming space and live rock territories, a 125-gallon or larger aquarium is required. While peaceful with other fish, this Tang is hostile towards other Tangs and Surgeonfish. Although the Tang will eat meaty foods alongside other fish in the aquarium, it is essential to provide them with plenty of marine-based seaweed and algae to enhance their overall health and reduce aggression. Offering dried seaweed tied to a rock or a veggie clip at least three times per week is recommended. Sea Veggies, Seaweed Salad, and Ocean Nutrition are all convenient and excellent options. These fish are ideal for managing algae growth in saltwater fish or reef aquariums.
