Hey everybody, I'm still looking forward to getting a pet octo of my own :) My friend gave me his old aquarium, and it's pretty big. I'm not sure how many gallons, but it seems like it will be alot more than enough. Now i'm not sure where to start, what kind of water should i put it in, what kind of sand, any decorations? I know absolutely nothing at all about aquariums, so i'm not sure how to set it up properly to recieve the octo, though i know i will have to leave it a few months. What materials will i need to purchase? Thank you. Also, a few off-topic questions: What would be the good species of octos that are interactive? A decent-sized one, that lives for about 10 months, and that you can pick up or touch without it trying to kill you? :3 Also, is it possible to get one of these kinds of squids as a pet?
