Uh oh...

Just found a gorilla crab in my tank. I had ordered three fish ( two clowns and a gramma), and they are supposed to arrive tomorrow. Will the crab pose a threat to them? The fish are pre-quarantined, and I don't have the option to keep them in another tank while I get the crab out. The gorilla is only a little bigger than a quarter including legs, so I'm not sure if it'll be an issue. What should I do? Thanks!

As long as the fish aren’t tiny and don’t decide to sleep near it’s den, they’ll likely be ok. If you know roughly where the crab is, you could intentionally try to feed it to reduce its desire to hunt while you try to capture it. Maybe leave food in bottle near where you think it is.

I'd prep a bottle trap and leave it overnight for the crab... That way it's crab to sump, fish to tank, everyone's happy

You should ABSOLUTELY quarantine. Pre-Quarantine is not to be believed.

Should I put the trap on the rock, or on the sand? Thanks! The clowns are captive bred, so I imagine they'll be around an inch. Of course, knowing clowns, they'll probably stay high up near the overflow. It's the gramma I'm concerned about.

Thanks for the input, doesn't really answer my question though. The fish have been in copper for a month and come from a well known vendor, so I'm not too worried about that. If I ever add a fish from a less reputable source, I'll be sure to quarantine.

On the rock so it has an easy time getting in and a hard time getting out.

No it didn't. Just trying to help you avoid other problems down the road.

When there is one there is more, I would buy a hang on quarantine box and put all the fish in there until you are sure you have eradicated every last one.

You can go manually hunting with a red light at night and/or set a few bottle traps/shot glass traps.
