Mystery Crab Needs identifying....

[ScottyG87]

Hi Guys,

Today I was watching my tank while feeding and see something move under my mushroom rock, on closer inspection I found it was a crab. It must be a hitch hiker as I never purchased it. It's about 1 and 1/2 inches in size, with purple features and red eyes.
Can anyone identify what it is from my pictures and description?

Thanks

It's likely a xanthid species. They are very destructive. If you have a sump toss it in there.
