Purchased this "Pacific brown" assorted octopus. This is my second day of owning. I have included pictures in the bag. He hid in the den with the light off all yesterday and last night (read if I left the room dark for a day he would relax more.) He readily took a thawed silver side (ate half and mangled the rest) he has been roaming and showing me his adaptive camo for the past hour, and then returned to his den. I do not know if he was just curious about me, he seemed to follow me around the tank, as we observed each other. As well as an ID could anyone put a rough ballpark age on how old he may be. There are about 18-20 hermits and maybe 10 snails in his tank to snack on, but I am very happy to have seen him eat half of a 1.5" silver side.
