Not so dwarf hermit crab

[SilverGryphon]

So tonight I discovered one of my hermits, is not so dwarfish. I saw what looked to be slightly smaller than a golf ball turbo moving around, and when I looked closer saw it was a hermit. Tried to grab it and get a good picture, but it yeeted itself off the back of the rock work as soon as the shadow of my hand passed over it and moved out of reach. It looked like a scaled up red-legged hermit crab, but after some looking online, looks like it is a Caribbean Scarlet Hermit Crab. What I'm finding suggests it is reef safe, has anyone had one before and had any problems with them?

You need to put a chunk of food in a jar and catch this one so we can see it!

Big crabs make me worry, but I have heard that some hermits are generally reef safe. Like everything else, they are until they aren't!
