Life of Picasso Triggerfish

Life of Sea | Picasso Triggerfish (Rhinecanthus aculeatus) | In my opinion, this is a unique fish. This is also known as Reef Triggerfish, Humuhumu Triggerfish, Blackbar Triggerfish, Prickly, Kaputput, White Banded Triggerfish or White Barred Triggerfish. They are called the Picasso triggerfish because of the seemingly random splash of colors on its body. They are generally found in shallow outer reef habitats. Picasso triggerfish are commonly found in subtidal reef flats and protected lagoons. In wild, they live live in the Indo-Pacific region. You can see them from the Hawaiian islands southward to Polynesia and Australia, westward through Micronesia and Melanesia, through the East Indies including the Philippines, across the Indian Ocean, to the coast of Africa and the Red Sea. 

Picasso  triggerfish has a beautiful color. Its body is colorful, from tan or yellowish and becoming whiter underneath. The stripe's color is from blue-edged brown bar, yellow band and blue line running from the eye to the gill. Four narrow blue bands, separated by black, run between the eyes and across the top of the head. The eyes are positioned high on the head. The snout is long and pointed. The mouth is directed slightly upwards, with short, strong jaws. The lips are bright yellow, with a narrow, pale blue line and a dark reddish-brown streak extending from above the upper lip towards the pectoral fin. The skin of the Picasso triggerfish is extremely tough

Picasso triggerfish are carnivore. In the wild they prey on sea urchins and a variety of crustaceans. The Picasso triggerfish have sharp teeth and might bite if it feels threatened. Therefore, you have to have extra care when keeping them in aquarium. The Picasso triggerfish should be fed a varied diet. They can accept flake food and pellets.  It should consist of a variety of different food sources such as different types of chopped up sea food, frozen food, preparations for omnivorous fish, live food and flake food. You can feed them at least 2-3 times a day.


In the wild, the male Picasso triggerfish protects a territory with several females in it. Each female protects its own territory within the males' territory.  During spawning season the females dig a pit in which they spawn. This behavior makes it likely that a very large aquarium is required to breed Picasso triggerfish. Fry and larvae caught in the wild have proved very hard to raise.
