Is this "tropical lobster" as the LFS called it really reef safe? It seems a little rough on my toad stools, etc and I was wondering if I shoulg trade it in for something a little gentler. its about 4 inches long not including its antennas. It dosen't have pinchers however. Also, has anyone ever had garden eels, and are they reef safe and compatible with softies, tangs, and blenny's? If so, eating habits? any help very much appreciated, Chris
