It is my main goal to keep a healthy octopus in my 75 gal. tank. My parents are not too keen on the idea, as they really like the colorful fish. The tank will be in our den area, so many people will see it. I was wondering if it would be possible to put a divider in the middle of the tank so that the octopus was on one side, and the fish were on the other. I would make sure that there was no possible way for the octopus to get over to the other side and eat the fish. Is there anything else that must be done? My trickle filter is rated for aquariums of up to 150 gallons. I have found it a good idea to use things that are rated higher than what you're actually using them for. But you guys already know that. Any help would be greatly appreciated.
