Hello, I've always had an interest in octopus' and was just wondering the basics. As of now I have a 30 gallon tank from a freshwater aquarium i had a while ago. Is this too small? Also, I was wondering if anyone has had any problems with octo-escape artists. I've heard stories of them escaping tanks, any way to prevent this? Answers to these and any other common mistakes/problems you can think of would be much appreciated. (also, if anyone has any ideas for a good tank layout, that would be great.)
