OK, I haven't had much success getting Kitty (My octo) to eat frozen food. Just looking for a few hints here. I read online alot of people put it in a shell, where can I get a shell for it and what do I clean it with to make sure there are no toxins? Could I use a piece of clay pot instead? That might be a little easier. Are there any frozen formulas you guys recomend? I saw a formula for sharks and rays and thought that might work. I have currently tried frozen mysis shrimp. Keep in mind, He's very small, maybe half an inch.
