Big Eye squirrelfish....are my inverts at risk?

I helped a friend move his SW tank last night and he gave me a Big Eyed Squirrelfish (Hawiian). He seems very docile, as I have viewed him in my friends tank before. He is about 2- 2 1/2" long. I know squirrelfish like to eat crustaceans.. are my hermits, emerald crab, or snails, in any danger of being dinner???
Does anyone have any experience with these fish?
Thanks in advance....MCF


Squirrelfish eat snails, worms, shrimp, some crustaceans...they also get a bit big. Some of them reaching 10" while most top out around 8". They're very active swimmers and nocturnal.
