I should stay out of That Pet Place in Pa.....I have never seen an octopus totally flatten itself out on the bottom of a rock when you pick up the rock. The person helping me didn't see him on it as he was so well blended. I don't know what he is, but am thinking maybe some sort of dwarf species. He's only been in the tank 10 minutes and found one of the local crabs. Spike looks like a monster compared to this new one! Curled up he's the size of a 50 cent piece. When I was dripping him, I'd pick up his rock and you would see this little black blob, that would very sneakily slide his way back to his rock!
