Thanks, everybody! This forum is great for help.

Yes, by striking I was referring to striking at me. He seems to want to avoid trouble and doesn't seem to want to be aggressive toward me. When I got bopped by his nose (not struck) I'd just lifted the cover off his cage and startled him. He was probably asleep. When he struck at the rat, he moved so fast it startled me. I'm going to need larger feeding tongs when he grows a bit, LOL. Talk about moving fast!
