So I got this little fella, whom I've named Sir Octavius Spindlius, from Odyssey Pets in Dallas TX on October 2nd. Took them a year to find what is supposed to be a pygmy or dwarf octopus since I have a small tank due to apartment living. I think he's (or she if female) the greatest thing ever. But all the packaging said was "East Asia" and my roommate is itching to know what species he is exactly. So I'm posting here for ID help. His default color seems to be black with a white stripe down his head or off white/tanish. But as masterful as he is with changing colors and textures its hard to say for sure. First picture is from yesterday when he decided to wear black with white pocadots. Next two pictures was a few days earlier when he was yellow but still wearing the white stripe. He is all legs! His mantle/head is about the size of my thumb. But those legs can almost stretch from one end of tank to other. He's supposed to be tiny octopus. My biggest fear is he's going to outgrow the tank. He was missing two legs when I got him. Thankfully they are growing back nicely. Thank you for the help!
