Gold-rimmed Surgeonfish, or Whitecheek Surgeonfish, has a black-to-purplish-blue body that has tiny white marks across the cheeks between the eyes and mouth. The pectoral, anal, and dorsal fins appear dark blue, with blue highlights on the tips. Tail fins are blue, with an orange vertical bar. A yellow stripe runs across the body, contrasting with the dorsal and the anal fins, creating a distinctive wishbone-like marking. A 125-gallon or larger aquarium is sufficient to give plenty of space for swimming. It can be aggressive with other Tangs but is calm with the other aquarium fish. While Tangs can eat meaty meals alongside divers in their aquariums, it's crucial that they receive ample amounts of seaweed that is marine-based and algae. This will boost the immune system of Tangs, decrease aggression, and boost their overall health. Give dried seaweed that is tied to a rock, or the veggie clip, and feed them at least three times a week. Sea Veggies, Seaweed Salad, and Ocean Nutrition are all ideal products and are extremely simple to use.
