Overview

The Naso Tang, also known as the Orangespine Unicornfish, darkens with maturity. Naso Tangs from Hawaii are often more brightly colored than those found in other areas. As a juvenile, the Naso Tang from Hawaii is dark gray with a blue stripe following along the dorsal fin and an orange stripe in the anal fin. When matured, the body takes on a reddish-brown tone and the juvenile striping is supplemented with additional color. The tail takes on a lyre shape with a yellow vertical bar towards the back. Two orange patches appear at the peduncle spines near the tail. The face undergoes the largest change. A thin, black mask forms between the eyes and mouth. The mask is outlined with bright yellow and the lips develop a reddish-orange color.

A 180 gallon or larger aquarium is necessary to provide plenty of swimming room, and places to hide, with a tight-fitting lid provided to prevent jumping to escape. It is aggressive towards other tangs, but peaceful with other fish in the tank.

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.

I have a 6 inch Naso Tang and he is one of the best Tangs I have ever owned. He readily accepts live, flake, seaweed and any other food presented. He comes to the top when the cover is opened and allows me to pet him. This Tang is VERY strong and is resistant to disease. A great selection for a reef tank!
Johnathan S Somerset , KY
My Naso is a great fish. She is with a Yellow Tang and Humu and they get along fine. This fish loves food! As soon as I approach the tank, she is at the top whisking around.
Doug K Jacksonville , FL
This is one of our favorite fish! We have had our Naso for more than 5 years, and he is extremely personable and energetic. This species needs lots of vegetable matter in his diet (particularly brown algae, like the Seaweed Selects product). The Naso Tang is peaceful towards most other species, but may spar a bit with other surgeons and tangs (although ours only does a minor bit of sparring, nothing serious). Be sure to give this fish plenty of swimming space, and put him in a big tank -- he will grow quickly, given good water conditions and proper nutrition.

I bought a Naso Tang and love it! It grazes on seaweed and marine algae and swims a lot. It is an extremely peaceful and fun to watch fish.
William R Lilleton , CO
I have a large adult Naso in my 125-gallon reef tank, along with a Purple Tang and several other mild species. I added him last and he settled right in. He is great at keeping algae down, and loves valonia!
Doug H Massapequa Pk , NY
This fish is one of the best, especially for beginners! It is always swimming around the tank and has a great personality. It is usually non-aggressive. I would recommend this fish to anyone who wants a community fish tank.
Chris L Niagara Falls , NY
I love this fish, he literally follows my clownfish around like he is tied to him on a string. It's hilarious! Eats everything, including the nori I supplement. I haven't had much luck with tangs from my live fish store, but this fish seems to be perfect!
Mary M Kissimmee , FL
Naso's are definitely my favorite fish. Very hardy and peaceful. They are very friendly and get along with most other tankmates. Mine shares an overhang in my Live Rock with an Emperor Angelfish (they are together most of the time). She eats everything, especially algae. Good choice for a reef tank. They need a large tank, about 6 feet in length.
Joe L Tonka Bay , MN
I ordered a naso tang from here, and might I just say that it was the best purchase I have made for my tank. This fish brings mystique and color to my reef tank. I will most likely buy a blue powder tang from her too! Great purchase would recommend to anyone asking.
