Too large emerald crab an issue ?

[doaz]

Hi all
I have an emerald crab that use to be about 3/4 inch long and would rarely see him.
He's been molting and is now about 2" long and 1" wide. I now see him out between the rocks roaming around.
Should I be concerned that he will now start eating my fish or such?
I've noticed my snails disappearing or it seems like that to me.
Is he eating them?
The only other things I have in the tank are tang, 3 golbies, 1 fire fish, 2 small clowns, bubble tip annenome and zoas.


Thanks
Kevin Baker

Opportunistic feeders doubt he is catching fish though....

Should be fine for now but heard big ones could injure small fish
