The Blue Throat Triggerfish, also known as Bluechin Triggerfish, or Gilded Triggerfish, is grayish-brown, covered with light-blue spots. The fins are edged in yellow. The male of the species has a darker blue area on the cheeks, hence the name Bluechin or Blue Throat.

A 125 gallon or larger aquarium with rocks and caves provides a good environment. The Blue Throat will rearrange the landscaping and rocks. It is said to "talk," which is actually a grunting sound.

The Blue Throat Triggerfish needs a varied diet of meaty foods including; squid, krill, clams, small fish and hard shelled shrimp to help wear down their ever growing teeth.

What a great fish! I have her in a predator tank with a Picasso and a massive Zebra Moray. The Picasso has taken quite a liking to her puffing up, displaying his trigger and swimming (sometimes upside down) very close to her.

Great colorfull fish. One of the best triggers Ive ever owned. Very peacefull, even around small fish. Just enjoyed swimming back and forth in my tank. Kept to itself, never bothered any other fish. Only problem is when it locked itself in the rocks. Overall, amazing fish to have

I have a pair of these great tank mates with my larger angel fish, magnificent foxface, snow flake eel, maroon clown fish, spotted sweet lips, Achilles tang, rectangular trigger and bursa trigger in my 500 gallon sps coral reef I recomend these guys for a reef if anyone has. I added last year a 3 inch 4 stripe damsel and he seems to be more aggressive then everyone else and they seem to leave him alone.

I really like trigger fish, but I have corals in my big tank so I selected a Blue Chin. I have a beautiful 5" male in my 210 reef. He gets along with my tangs, clown, damsel, inverts... everyone! He knows the feeding routine, smaller bits first, then he will show up for the bigger bits of food. He will even eat krill out of my fingers. I have heard that these triggers can be jumpers. Mine did jump from the tank. He was out of the water for about a minute! I put him back in, he hid for a few hours, and then was fine. He has not jumped since. I recommend putting egg crate on the the top of the tank just to be sure. Also, he has a nice cave staked out, be sure to have a place for him to hide in your tank. If you have a reef, this is the trigger to get!

I love this fish! I bought a male blue throat about a year ago. I was skeptical as to whether or not my tangs were going to accept him or not even though my tank is 225 gallons. Once I put him in the tank, no one bothered him. Later, I added an emporer angel and the angel is the only fish that chases him once in a while. The trigger is peaceful with everyone and minds his own business. A beautiful fish, and quite the hungry hippo. He loves seaweed/nori and mysis shrimp. I highly recommend getting one of these triggers. I do agree with Liveaquaria with the recommendation of tank size. My trigger loves the ample swimming room and loves his cave.
