Has he warmed up to me yet?!.......well just after I shot that video this morning I stuck my hand in the tank to remove that little PVC fitting you can see in the video, it was one of Leg's toys and its been bouncing around the tank un-played with for too long. Pen immediately charged over to my hand and proceeded to blast me with his cannon while displaying his defensive colors and position with all his arms and webbing out but curled in at the end...so basically no. He has stopped trying to grab me and bite me which is good, but he still doesn't prefer my company...I miss Legs, such a great octopus.
