Good or bad acro crab

[twiggyb]

Found this little guy tonight, don't want to get rid of him if he's ok, but I'm leaning more towards no. Can anyone tell me?

This is the acro he was in

I would remove it immediately.

I have one in a large colony that I have had for 3 yrs. It is eating and destroying it. I am thinking of breaking it off at the base and dipping it. The dip most likely will not kill it but it will make it possible to shake it out of the colony.

I used revive on one and it did stun it enough that it fell off the colony. I think it eventually died as I never saw it in the sump again.

Try attaching a sowing needle to a thin wooden dowel and harpoon him to death? Dipping will not work on him trust me I know,

I have used long thin tweezers to remove crabs like this. They can be hard to get out!

Cymo melanodactylus. Most would remove the crab.
