So I've really wanted an octopus for a while, but I can't seem to find any straight answers. I have a few (thousand) questions. 1) What is the smallest octopus I can get? 2) Do all octopus bite? 3) What is the smallest tank I can get for the octopus? 4) Where would I look to purchase an octopus, and about how much should I expect it to cost? 5) Where should I purchase food, and about how much is food? 6) How often should their tank be cleaned? 7) This souds silly, but are they friendly? Alright that is about it, for now haha Thank you!
