I got an octopus via my LFS just last week! I have been waiting to post about him until he was coming out of his den and could include some pictures and video. This morning, he finally did! This is Pete. He was sold to me as a Vulgaris and, if he is, he is just a baby! His mantle is maybe a couple inches (at most). All I really know about him is that he was sourced from the Caribbean. I've already observed some interesting behavior (which is shown in the pics). I must have startled him this morning because his reaction was to stock his mantle straight up and away back and forth. I think he was trying to look like algae. :-D I am concerned he might not be a Vulgaris. I know there's a possibility he is a mature dwarf, but I'm hoping I won the lotto and got a baby Vulgaris. Perhaps someone could help me positively ID him? Without further ado, here are some pictures!
