General information:
The Triggerfish are a very beautiful group that is very strong and aggressive.  They have enlarged heads with fat bodies.  Their powerful jaws allow them to chew through just about anything.  They are recommended to be kept in a tank with other fish that have similar aggression because they can be hazardous to others.

Special anatomical, physiological
or behavioral adaptations:

When threatened by a predator Triggerfish will dart into a hole or crevice in a reef.  They do this by locking the dorsal spine erect and depressing their pelvic bone to wedge into the reef.

Comments about the blue-lined triggerfish of the Fort Worth Zoo:
When watching the triggerfish I noticed how they are very alert but graceful.  They are rather pleasant to watch since their colors can be extraordinary!  Check them out! 

Personal Observations:
The triggerfish are very colorful fish that are a joy to gaze at in the aquarium! They are not very hard to spot out since their brilliant colors make them stand out!
