can anyone tell me if an octopus will eat another octopus? today i received a nice little 1" bimac from Jack @ fishsupply.com. about 2 minutes later, the funniest thing happened! BOB IS BACK! i left the room for 2 minutes and came back to suddenly find 2 in my tank! i'm sooo happy he's alive, but now i'm worried because bob is about 1/2" - 3/4" and Bob II is a full 1". The big one keeps jumping on top of the little one and then the little one slides out from underneath and they run apart. is he going to eat him? or are they just playing? thanks.
