His tank has a flat sheet of plastic in place of a hood, with a little opening to feed him through. He'd have to aim pretty carefully to jump through it. I've never had a betta who jumped, but should I put a little something over the hole just in case? There's a couple of other holes in the plastic that are too small for him to jump through, so there would still be airflow if I blocked the big one.
