Octopus are a wonderful creatures to keep JD, you are doing a fine job. As you have already discovered, they are the masters of escape. It is a fact that if you can fit a pen through a gap, the octopus will also get through.
It saddens me to read some of the negative remarks that have littered you thread. I find it ironic that I have mentioned on the open forum that I feed my G. Funebris live octopus, and I have not received ONE word about cruelty. So why you are being accused of being cruel is a mystery to me. I wish you well with your new project.
Peace.
