Trigger attacking inverts?

Is this normal for him to do that? He is attacking my hermits..didn't know if this is bad or what? Just don't want him to kill my inverts
 
It is a Humu Humu, he has been in there a couple days, since I have got my levels just right, then I just added some blue leg and scarlet hermit crabs, and he is trying to pick them up and nibble at them.

Okay, thanks. First off...Humu Humu's are not reef safe. Second, they are known to pick up "things" and move them around.
Is the behavior more of an aggressive nature, or is he just picking them up and moving them somewhere? Either way, you will have to keep him very well fed, and still watch out for aggression.

I'm not aware of a reef safe trigger. They fall under the "aggressive" category. If they can eat it, they will. If they can't at first bite, they will continue trying.

Crosshatch...for the most part.

triggerfish are purpose built to feed specifically on shelled crustasceans. they arent natural piscivores (they may eat fish but they dont hunt for them) and only a few are plantivores. it's whats for dinner! crabs, shrimp, lobster, mantis ect is pretty much ALL they eat naturally. Blue throats and crosshatch are the ONLY natural zooplankton eaters (that I'm aware of) and the only ones you might put in expecting not to have your clean up crew cleaned up. a few others like the pink tail are less likely to dismantle and reaquascape your reef and harrass tank mates but they still eat crustesceans.

I have a Pinktail and Picasso Triggerfish. Before I bought them I removed, (I thought I removed), all the inverts such as clams, snails, crabs and so on.
Guess it goes without saying I saw a few peppermints run for their lives to no avail. I did manage to get a couple out at the last minute.
It's funny to watch the Melichthys indicus (Humu Humu Triggerfish) pick up shells and move them around. The teeth grow as they do and if I remember correctly, continue to grow partly why you might see some of this action in an effort to keep teeth normal. But, they will crack open a shell to eat a hermit or snail. It's not that they are entirely mean...Just hungry. Look how quickly they grow.
The older my Pinktail gets, the tamer she is. The older the Picasso gets...not the case. Just my 2 cents worth.

As far as I know there aren't any triggers that are 100% reef safe but there are a few that are called reef safe. The crosshatch, blue jaw, pink tail, & sarrgussm. I've been researching reef safe triggers I'd like to try one out. I've heard the blue jaw is considered the most reef safe...but with triggers it's kinda hit n miss...just depends on the fish.

THis is normal natural behavior and diet for triggerfish. It is not reef safe and is a threat to shrimp, crabs, snails, seastars, brittlestars and other inverts - if not by eating, then by moving them around.
