Purple little crab in my live rock

[Dornenkrone]

Hello I recently seen a little purple colored crab in my live rock. No fish have died but I'm scared it might be dangerous. I cant get a picture of it but its about the size of the tip on my finger. It has a very smooth shell and i cant see the claws. Anyone know what this is?

If it has pointy black claws get it. That's a bad sign. Other than that I cant tell you much. Porcelain crabs sometimes have a purpleish hue to them. They are good.

Its really tiny like I said cant see the claws. It stays hidden in my live rock pretty good. Like right now i still cant find it, I tend to see it at night.

Tip a pint glass against your rocks with food in the bottom overnight. You'll catch all your crabs.

Does the pint glass thing really work? Do i need to worry about anything else getting stuck in it?

You should be fine with the pint glass
