Hey, i dont know wether to say its cool or its just alright...the idea of him is awesome, and the way he moves, eats, roams is cool. But i have been watching the videos and it looks like he just wants to stick on the glass...IMO i think it ruins the aquarium, when you see in the upper right hand corner a sleeping octopus...maybe he's just hanging out in the refuge...sure would like to see it in a larger tank. I thought about an octopus a few times.
