After doing some research, I would like to venture out into octopus territory. I have never kept a full marine aquarium, but have a Moray in brackish. My Moray is going to need a tank upgrade in six months, and I was wondering if I could convert this old moray tank to an octopus tank. It's just an idea, and I would never consider attempting this if it ment possible danger to the octopus. The tank is 29 gallon standard tank. If someone could provide me with additional materials nessesary to perchase, including filtration, substrate and lighting, Or if this is a silly venture, just tell me to wait.
