I might tend to agree with you. I found one similar to this as a hitch hiker from a piece of coral I got from All About Fish...except his back was just barely hard....like maybe it was growing a shell. I compared the markings on its body and it looks like a baby turbo to me. I figured if Kevin had these guys in his SPS tank without issues, it would likely be ok in my tank. It stays on the glass and seems to be growing a shell....I am keeping my eye on it though.
