Chevron Tang Care Guide
Scientific Name:
Ctenochaetus hawaiiensis
Other Common Names for the Chevron Tang:
Hawaiian Bristletooth Tang - Hawaiian Kole - Hawaiian Surgeonfish - Black Surgeonfish 

Description:

Chevron Tangs are found throughout parts of the Central Pacific Ocean, namely the Hawaiian Islands. They have also been sighted as far west as Micronesia. As juveniles, these fish are dark, brilliant orange in color, with blue chevron marks on their sides. These chevron marks are how this tang received its name. As the Chevron Tang  matures, its body will turn a very dark brown with thin, olive horizontal stripes. They will use their spines as a weapon against other fish that threaten them. Chevron Tangs can reach up to 11 inches in length and requires an aquarium of at least 150 gallons with live rock and plenty of room to swim.

Diet:

Tangs, in general, are primarily herbivores. These, in particular, belong to the Genus Ctenochaetus, so named for their bristly, comb-like teeth ( "cteno" = comb and "chaetus" = bristle). These little teeth make eating filamentous algae a breeze. That said, they need rocks to graze on as their diet is primarily marine algae. For tanks on the smaller side that have less live rock to grow algae, you will need to supplement your tang’s diet with Nori or other vegetable matter like Nori, Romaine lettuce, spinach leaves, or broccoli. They also will accept flake foods and sometimes small meaty offerings like Mysis shrimp. A good variety of foods will keep your tang healthy and vibrant. A well-fed tang won’t pick at your corals, but there is always a possibility if there is no algae or Nori present. Also, a well-fed tang has less chance of developing HLLE (Head and Lateral Line Erosion). HLLE can be fatal depending on severity and can leave lasting scars on the tang.

Behavior:

As stated earlier, a Chevron Tang can reach up to 11 inches and requires an aquarium of at least 150 gallons with live rock and plenty of room to swim. Tangs, in general, will spend their days swimming from one side of the aquarium to the other, picking on any algae growing on your live rock or frag plugs. In the ocean, tangs swim great distances every day. This should give you an idea of how much swimming space a tang will need to be satisfied in your tank. It is also recommended that your tank be wider than it is tall, to allow them more space to swim. Without ample space to swim, a tang can become stressed and will be very prone to diseases like Ich.

Chevron Tangs are mostly known to be peaceful with other tangs and other fish. With the spines built into their tails, they can usually defend themselves against other more aggressive fish. Keeping your Chevron Tang well-fed will reduce aggression in your reef. If you intend to keep fish, a netted lid is recommended.
