The Redtoothed Triggerfish is also known as the Niger Triggerfish, the Black
Triggerfish, the Blue Triggerfish and the Purple Triggerfish. The color
varies from blue to purple to black, even on the same specimen and the teeth are reddish.
It lives in reef channels and areas of strong current in the central and western
Pacific and in the Red Sea. It has a distinctive lyre tail. Triggerfish have a double dorsal fin with a large spine
or trigger 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
In the wild, the Redtoothed Trigger feeds mainly on mollusks and crabs.
The Redtoothed Trigger can be fed 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.
Although it doesn't eat coral, it is known to damage them. Triggerfish
use their mouths to blow over invertebrates and attack them in their soft undersides. They
can be very aggressive when eating. Be careful, as they will bite
hands. The tank should be a minimum of 75 - 100 gallons. It should have plenty
of places to hide plus open areas for swimming.
Redtoothed Triggers are very resistant to disease. There are no known sexual differences.
Redtoothed Triggers are egg layers and they are not
bred in captivity.
