my octopus finally arrived today, its roughly a foot long. i asked for a cyanea and i believe thats what it is. the webbing between its membrane goes a large way down its arms and its already used them to cover some live rock and catch a crab which i know is something cyanea does in the wild. that dirty looking stuff at the bottom is live sand that my pump picked up and i haven't been able to entirely remove yet. any comments would be appreciated.
