Thoughts on arrow crabs

[wetone]

Well...????
I have one in a 70G tank with lots of LR and hiding spaces. I have not seen him do any damage, I've only seen him pick at the sand and LR, BUT I can't seem to keep hermits in the tank. I have heard that arrows will bother any other type of crab..

Yes, an Arrow can and will eat hermits. A friend of mine watched his Arrow jump off a rock and encircle a Royal Gramma and kill it.
