The Yellow Eye Bristletooth Tang (Ctenochaetus marginatus) require a 70 gallon or larger aquarium to provide plenty of swimming room. It is aggressive towards other Tangs, therefore, it is best to only keep one per tank. It will not harm sessile invertebrates in the reef tank environment.
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.
