This fish is a stunning sight with its bright orange tail and spotted pattern. It’s a rare find and very different from the standard undulated trigger. I was excited to see it in the aquarium and it stands out among other species.

The Xanthic variant is visually striking. The spots and orange tail spines make it unique. It’s a bit harder to spot in a group, but once you notice it, it’s hard to look away.

I’ve seen many triggerfish, but this one is truly special. The coloration and pattern are unlike anything else. It’s a great addition to a reef tank with a focus on rare species.
