Little Bit (who is now way larger than Espy) has continued to interact by playing tag and typically only wants a quick touch. Her touch an go is a lot different than most of the octos I have handled and seems more of an entertainment than curiosity. I have a few video pieces of her flying around to tag but have not yet really captured the oddity of the game. Tonight, however she started her game of tag but then went to the upper corner of the tank and came over to my had a couple of times, allowing me to pet her. With females, I particularly worry about a change in behavior. It always seems that the ones that don't quickly decide to come to be petted make initial attempts just before brooding. I really hope we are not that close yet as she has been really delightful to keep and I highly recommend species for a home aquarium.
