I'm not sure, but how many times have you seen an LFS guy say " its a brown octopus, vulgaris, oh your new to the hobby! great there super easy! $100 each super rare!!!" I'm not saying saltwaterfish.com does that because I have gotten fish from there several times and had no problem. Second best fish dealer I now. great shipping. But octopus do get mixed up often especially because of the fact that they change color and texture!
