Emerald crab

Has anyone experienced an emerald crab being aggressive toward fish? I have seen him eat a six line wrasse, dottyback and now my cardinal fish? I have been feeding them every other day frozen mysis shrimp. Any advice?

What are your parameters? Are you sure the fish aren't dying and the crab is cleaning up the mess? I've always kept them and haven't ever seen one catch a healthy fish.

You've actually seen it catch a healthy fish? Or just eating the body?

Parameters are fine.
Ammonia-0
Nitrites-0
Nitrates-20
Salinity-1.025

The fish are healthy and acting fine. I haven't seen him catch a fish swimming around. I have seen him swipe at the fish. I just got home and see him eating the cardinal. All the fish appear to be very active and healthy

Didn't think it was normal for them to catch a fish

I doubt it actually caught any fish, sounds like you have something going on in the tank causing the fish to die and the crabs just being a crab.

I have watched them stick out their claws in a defense manner, but never lunge at fish. I have seen sally light foot crabs do this though. I suppose it's possible, but unlikely.

Is it possible he was hungry and got aggressive?

But that hungry? I suppose it is, but you said you were feeding it.
