I thought I would post a follow up for this. As it turns out, the lionfish prefers food that doesn't move at all. Not even floating by. He wants it on a skewer, hand delivered. Though he will chase the skewer a bit. His eyesight is good, because he will follow food that drops with his eyes, but he won't go after it. He's a princess, it seems! Serfs, bring me my suppa!
