I agree. I have had a couple of Car Reef octos and a merc. I will never do a merc again unless the tank is in my bedroom. Never see it during the day. I am on the hunt for a Vulgaris. The first octo I ever had was a vulgaris and he was fantastic. So much fun, Big, and so much personality. I kept him in a way to small tank but he did great for 16 months. Tank was a 40" 50-60g and he could easy reach side to side. His color changes were great and so fast. It was also 17 years ago before Tonmo and all the info we have today on them. They have become hard to find.
