Lieutenant Tang

Greek Name: (Acanthurus tennenti)



The Lieutenant Tang is a reef fish in the Maldives Islands and is mostly brown with darker lines that outline its body. The scapulae is outlined in a bright blue and also its outline on the anterior fin. The tail, if it is mature enough will appear to have an angular appearance as trailers develop.

A 180-gallon or bigger aquarium that has large quantities in live rock are essential to ensure ample swimming space as well as areas in the rock. It is aggressive with the other Tangs and Surgeonfish however, it is calm with other species of fish.

While Tangs are known to eat meaty food as do divers in their aquariums, it’s essential that they get ample amounts of seaweed that is marine-based and algae. This will boost your immune system and decrease aggression, and boost their overall health. Provide dried seaweed that is tied to a stone or the veggie clip, and feed them three times a week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are extremely user-friendly.
