I got my octopus this morning from saltwaterfish.com. He's pretty little. I dripped him for an hour and a half and now's he's movin' around my tank. He started flashing colors right when I put him in. Then after watching him for several minutes, I picked up the camera slowly and he changed dark brown and put his mantle up and pointy. They tricked me by putting a black bag around him; I thought he inked! Pictures are dark so I need to make them lighter, but I will post some soon. I believe Animal Mother's guess of O. Filosus, the Caribbean two-spot Octopus, is correct.
