The Picasso Triggerfish or Huma Huma Trigger (Whitebanded Triggerfish or Painted Triggerfish) is very popular probably because of its’ very interesting color and unusual patterning.

It is quite striking with the line markings of yellow, blue and black adorning a mostly white body. This fish will emit a ‘whirring’ sound when it is startled.

To maintain a peaceful tank that houses triggerfish, be sure to provide lots of room and a cave or rocks for a retreat area. Also house-appropriate fish together that have similar needs and can hold their own. In this case larger protein eaters such as groupers, surgeonfishes, and basses, Some eels and puffers can be appropriate too.

The Picasso Triggerfish or Huma Huma Trigger are known to have a pretty good disposition for a trigger and are generally a peaceful fish.
