Are you interested in learning about different fishes like cory catfish? In this article, we will learn about the bluethroat triggerfish (Xanthichthys auromarginatus).
Blue throat triggerfish are also known by the names, gilded triggerfish, blue jaw triggerfish, and blue chin triggerfish. All these names have been given to this species due to the vibrant and striking blue patch present near the throat of a male blue throat fish.
The blue throat or the blue jaw, like most triggerfish, has the ability to keep its dorsal spines fully erect. This species has its origin in the Indo-Pacific Ocean where it lives in open bottoms and feeds on a variety of plankton.
The male and female differ from each other in appearance. The male has a distinctive blue patch while this patch is missing in the female but what makes it attractive is its grayish white spots.
The blue chin fish also has yellow bordered fins. These yellow fins provide a stark contrast to their blue bodies and make them appear to be very attractive.
The blue chin fish can be easily kept in a tank as a pet and can be fed normal aquarium foods. They are believed to be reef safe but due to their semi aggressive nature, their suitable tank mates would be similar sized fish.
