The Niger Triggerfish, otherwise known as the Redtooth Trigger, vary in color. They are known for changing in color (day to day). One day, they can be blue with lighter blue highlights on their fins, the next day they can be purple. The changing of their coloration is due to the temperature of the lighting in the aquarium.
It is best to house the Niger Triggerfish in a fish-only 180 gallon tank or larger with caves for hiding and rocks to stimulate a natural habitat. These fish tend to rearrange the landscape while maneuvering around the aquarium, and should not be kept in reef aquariums.
The diet of the Niger Triggerfish should include: krill, clams, small fish, squid, and hard shelled shrimp to soften their teeth.
