I'm not sure if they would eat the fish or not. But if they caught one, I'm sure they would take a nibble.
I can't let them out before I put the trash can out or they will knock it over and get trash everywhere. If there is a bag anywhere they can get to, they will get in it and they LOVE to get in the shelves with my shoes and knock them down. And all of this is in my bedroom, I don't know what they would do if I let them run all over the house. Oh, I did leave them in the bathroom once and they found my box of tampons and they were all over the bathroom. Gotta love em.
My birds aren't too bad about tearing stuff up but I know that they can get into trouble sometimes.... but it's so much fun for them, right?
