Reef Triggerfish - Origins
The Reef Triggerfish is also known as the Wedge-tail Triggerfish, the
Rectangular Triggerfish and the V-line Humu Humu. It is
often confused with the Picasso Trigger.
The Reef Triggerfish is the official fish representing the state of Hawaii.
The name Humu Humu (triggerfish) comes from Hawaiian and Humuhumu-nukunuku-apua'a refers to
the pig-like snout that it and the Picasso Trigger have and use to
"root" around the reef. The Reef Trigger frequents the outer
edges of coral reefs
of the central and western Pacific, including the Red Sea. It has a tan body with dark bands.
Its distinctive features include blue/black strips across its eyes, blue lips and a black wedge at the base of the caudal fin, which is outlined in brown
and yellow. The Reef Trigger is highly maneuverable and changes directions
Reef 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. Triggers have been known to sleep on their sides as well.
Reef Triggerfish - Aquarium Care
The Reef Trigger is reasonably easy to keep, but is not reef safe and is not a good community fish.
Reef Triggers 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.
Reef Triggerfish - Feeding
In the wild, Reef Triggers feed on algae and invertebrates. In
captivity, they can feed 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. They will bite fingers, but can be
hand fed. They will also disturb items in the tank.
Reef Triggerfish - Breeding
There are no known sexual differences. Reef Triggers are egg layers and they are not
bred in captivity.
