the claws are pointed. the legs are hairy they have black dots on their brownish colored bodies

That sounds gorilla crab like but it doesn't look like a normal gorilla crab. That would be a toss it out crab.

The fact alone that its hairy is a No-No for your tank.
Looks like a pebble crab or rock crab, but my best guess is granulated Xanthid crab

Sounds like a Xanthid then likely. Can be nasty little critters
