Check online for fish traps. Also, you can wait an hour or so after you turn out the tank lights and search the tank with a red lens flashlight. Once you find the octo, you can try to capture with a net.
Also, to fully be able to help you, I'm gonna need a larger picture of your avatar.
Further if u try to capture in a net and is releases ink is this going to affect my other occupants???
