Soon I will be attempting to keep a few octopus (not sure about the species yet) for research/academic purposes. I have no experience at all with octopus. The aquarium I'll be using is one of many that is fed by a main supply of reverse osmosis water. It has been running for quite a while, and should be mature. I know I will need to cover the top, and monitor the water quality, but what other steps do I need to take before I introduce the octopus? I'm interested in a few helpful hints!
