Triggers making grunting sounds

[snapcrackler]

Do your triggers really grunt like a pig as they are said to do, or is this just when they're agitated?

I think that would be weird to hear that.

If you had a pistol shrimp in your tank too, then it would be like oink, pop, oink, pop....

I've heard them grunt, and I had one once that would come to the surface and spit water at you when you opened the lid.
