I have seen a couple midas blennies in stores, and all look like the one in the second pic. I think the one listed on this website was just an extraordinary example. I wish they all looked like that!
You are'nt permitted to post other online vendor's sites here at SWF. But to answer your question, the one in the photo here is a real fish with his stress colors on. This fish stresses easy. The one at LA is an artist's rendition of the same fish. Make sure you have an enclosed top, this fish is a jumper!
I suggest you remove the link or delete this thread.
