The horned bannerfish, also known as the humphead bannerfish, is a cool marine fish. It's a type of butterflyfish and lives in the warm waters of the central Indo-Pacific ocean. This fish gets its name from the unique "horns" on its head!

What Does the Horned Bannerfish Look Like?
The horned bannerfish is a small fish, growing up to about 19 centimeters (7.5 inches) long. Like many butterflyfishes, it has a body that is quite tall and flat, almost like a pancake!
What makes this fish special are the two clear "horns" on its forehead, right above its eyes. It also has a noticeable bump on its forehead. Its body is mostly brown to black. It has two thin white stripes. One stripe is behind its head, and the other runs from its back fin (called the dorsal fin) down to the narrow part before its tail (the caudal peduncle). These two white stripes create a cool triangle shape of the darker color on its body. The fin on its back has 11 sharp spines and 22 to 25 soft rays. The fin on its belly (called the anal fin) has 3 spines and 17 to 18 soft rays.
Where Does the Horned Bannerfish Live?
You can find the horned bannerfish in the warm, tropical and subtropical parts of the central Indo-Pacific ocean. This area stretches from Indonesia all the way to Polynesia, and from southern Japan down to New Caledonia.
This fish loves to live in places with lots of coral. It hangs out in shallow lagoons and on the outer slopes of coral reefs. You can spot them from the surface of the water down to about 30 meters (100 feet) deep.
Horned Bannerfish Habits and Diet
The horned bannerfish usually swims alone. However, sometimes you might see them in pairs or even in small groups.
They have a varied diet, meaning they eat different kinds of food. They especially enjoy eating tiny parts of coral, called coral polyps. They also munch on various small creatures that live on the ocean floor, known as benthic invertebrates.
Who Named the Horned Bannerfish?
The horned bannerfish was first officially described in 1829. A French scientist named Georges Cuvier gave it the name Taurichthys varius back then. The first place where this fish was found and studied was Ambon Island in Indonesia.
Is the Horned Bannerfish Endangered?
Sometimes, people catch the horned bannerfish to keep in aquariums. However, this species is not currently in danger. The IUCN (International Union for Conservation of Nature) lists it as a "Least Concern" species. This means there are plenty of them in the wild, and they are not at risk of disappearing.
