hey this is rivercity Leadership Academy (highschool)and We were interested to have a class pet octopus. I do realize that this is not another hamster that is going to die. We are trying to get a pet that needs hard work to keep and maintain. We are trying to put this to educational uses and a fun activity too. Do any of you guy have any suggestions before I look into this. Just one quick question about how much would and octopus that is small enough to live in a 50-100gl tank(sorry for the noob question im not here for you guys to tell me everything about how to keep an octopus I'll try to learn as much as I can by my self) cost?
