Anthias fish are small, colorful fish that are commonly found in the tropical waters of the Indian and Pacific Oceans. They range in size from around 2-6 inches in length, and have a distinctive, elongated body shape with a large dorsal fin and a forked tail. 

They are generally brightly colored, with patterns of red, orange, pink, yellow, and blue.

Anthias fish are found in a variety of marine habitats, including coral reefs, lagoons, and shallow coastal waters. They are often found in large schools, with males establishing territories and defending them from other males. 

They are typically found at depths of 10-100 meters, and prefer areas with plenty of coral and other structures to hide and shelter in.

Anthias fish are omnivorous, feeding on a variety of small crustaceans, zooplankton, and algae. They are known to feed on a wide range of prey, including copepods, shrimp, and other small invertebrates. 

They have small, protrusible mouths and sharp teeth, which they use to catch and eat their prey.

Anthias fish are known for their vibrant colors and active behavior. They are often seen swimming in large schools, with males establishing territories and defending them from other males.

 In addition to territorial behavior, anthias fish are also known to exhibit complex social behaviors, such as forming hierarchical groups and cooperating in group defense. 

They are also known to form spawning aggregations, in which large numbers of fish gather to mate and release eggs and sperm into the water.

Anthias fish are members of the family Serranidae, which also includes groupers and basses. 

There are over 200 species of anthias fish, which are divided into several genera, including Pseudanthias, Nemanthias, and Scolopsis. 

Within these genera, there are many different species, each with its own unique appearance and behavior. Some of the most well-known species include the:

  • square anthias (Pseudanthias squamipinnis) 
  • lyretail anthias (Pseudanthias squamipinnis)
  • harlequin sweetlips (Plectorhinchus chaetodonoides)
