Mystique showed some sign that she might have recognize me and not others today. For the past month me, my daughter, husband and even my 2 year old who runs up to the tank and sticks his face to the tank and at times taping the glass can approach the tank with out concern. We all can do this and Mystique will stay out on the tank or rock or where ever she may be. Until this morning. I have a friend who I have been trying to show my octopuses to for weeks. Today I waited to feed Mystique so she would be out when my friend got here. The second my friend got with in 10 feet of the tank Mystique immediately froze and went back into the rock. Which leads me to wonder... do they actually recognize some as safe and some as the unknown and there for not safe? Has anyone else had experience with this? I have read of others not having this kind of response so I am curious as to what others have seen. Additionally: This is also a high traffic area leading into the kitchen but sitting in our dining area where we eat.
