Picasso Triggerfish
Picasso Triggerfish - Names
The Picasso Triggerfish is also known as the Blackbar Triggerfish, the Lagoon Triggerfish, the
Whitebanded Triggerfish, the Painted Triggerfish, and the Humu Picasso
Triggerfish. There is widespread confusion with the public between the
identification of the Picasso Trigger and the Reef
Trigger, Rhinecanthus rectangulus, which is surprising as it is fairly easy
to tell them apart. The name Humu Humu means "triggerfish" in Hawaiian
and Humuhumu-nukunuku-apua'a refers to
the pig-like snout that it and the Reef Trigger have and use to "root"
around the reef.
Picasso Triggerfish - Origins
The Picasso Trigger comes from shallow coral reefs and lagoons
of the central and western Pacific, including the Red Sea. It has a tan body with dark bands.
It has bright black and blue stripes on the top of its head and a yellow stripe from cheek to
cheek. The eyes work independently to scan the reef.
Picasso Triggerfish - Anatomy
Triggerfish have a double dorsal fin with a large spine in the front area of the fin. It
uses the spine to lock itself into rocks and corals where it sleeps for the night, well protected
from predators. Picassos have been known to sleep on their sides as well.
Picasso Triggerfish - Aquarium Care
The Picasso is reasonably easy to keep, but is not reef safe and is not a good community fish.
Picassos are also territorial, so it is best to keep only one in the tank. They are less
aggressive than the Clown Trigger and a good choice for your first purchase of triggerfish.
The tank should be a minimum of 75 gallons, with 140 gallons preferred. It should have plenty
of places to hide plus open areas for swimming.
Picasso Triggerfish - Feeding
The Picasso Trigger feeds on regular live, frozen and flake foods. This can include squid, shrimp,
krill, mussels, pieces of fish, starfish, sea urchins, shellfish and small fish. Their diet
can be supplemented with spirulina, algae, dried seaweed and quality flake foods. Triggerfish
use their mouths to blow over invertebrates and attack them in their soft undersides. They
can be very aggressive when eating.
Picasso Triggerfish - Breeding
There are no known sexual differences. Picasso Triggers are egg layers and they are not
bred in captivity. The females builds a nest and cares for the eggs until they hatch, as well
as looking after the newly hatched juveniles.
