Odonus niger commonly known as the Redtooth triggerfish or the Blue trigger. Their origin is from the Indo-Pacific Ocean and from a depth of 5-40 m and can grow up to 19 inches in length. This vibrant fish changes its colors and can be found in electric blue, pink or dark blue.
Redtooth triggerfish has a very different way to swim in the aquarium tanks like most of the triggers they also have fins on the end of its body which is different from other fish. This fish is an easy to keep fish but can be aggressive sometimes towards other tank mates. As soon as we introduce the trigger in the tank most of other tank mates just hide away in the beginning.
