CBS can kill Pederson?

[Reef Breeder 2013]

My LFS has an a Pederson right now, and I would love to see an a Pederson walking around my BTA. The problem?: my CBS (she's 2 inches long in body. With his tongs 3 ½ inches).

I have an a peppermint shrimp of about 1 ½ inches with my CBS and they live "in peace". But, I checked the max size of an a Pederson and they are PRETTY small (1 inch).

Soo, what do you think?
