Will my Arrow Crab kill my fish?

I just got an arrow crab today, the guy at the aquarium place told me it would be okay in my 30 gallon tank. After a couple hours I came back to find it munching on my green chromiss. The chromiss looked like it had been sick for a while so I don’t know if the crab attacked it or just found it dead.

So the real question is will by two clownfish be ok, one is tiny, less than an inch and the other is about an inch. I also have a fire shrimp in there, Should I remove this crab
