ive had a bunch saltwater tanks but nothing crazy just some common sw fish and even coral, but the other day i was watching something on tv and they shown this house with a giant tank with all kinds of live rock and different types of coral and even a bunch of anenomies at first it look cool but nothing to crazy but out of nowhere from way in the back of the tank popped a awsome looking Octopus i dont know what kind it was but it was so cool to watch walk and hope around from rock to rock almost human like i was wondering has anyone ever had one??? and if so besides them be the best exscape artistsand having to be kept alone, how are they as a pet are the a very difficult animal to keep ?? i've looked online for info on them and found a bit but i could really use some advice from someone who sucsessfully had one or even knew someone with one, as many times what u see in books or online is a bit different from having to take care of one on ur own. any info would be most helpful thanks
