Tasty crab need ID!

It looks like one of the thunder crabs that you will find in our beaches. I think I will take out the whole rock. Soak the rock in plain water for 15 min - see if the crab will come out and then remove the rock quickly. Get rid of the crab.

Is it that bad? It's kind of beyond my reach to catch it.. Lol

It can get big (shell about 3.5" to 4" adult), strong enough to mess with your rock work if they're not secure and opportunistic feeder which might take (sleeping) fish and algae. (and maybe even coral?)

While it's still small you can use a 1.5l pop bottle to make a trap and bait it with market prawn or fish meat.

WHAT THE...that's so cute. and huge.and it's nice that you're not going to kill it.

Hard to believe that it might catch fishes during the night, its so shy when I try to hold it, doesn't even try to nip my hands with its claws! Going to feed it everyday with meaty food hope it will grow bigger! :pirate:

Reefing is sharing. People with rotten mouth is sure a loser for life as expected. When a tomato gets rotten, you can nvr save it.. Throw it away before it infect the good ones.
