He's hiding. One of mine will go into hiding for up to 2-3 days. It's the nature of the fish. However they are also known jumpers so if your sure there's no way he got out just keep your eyes open, he'll pop out somewhere
That's what I was hoping for. He seemed so settled in and comfortable that I was second guessing myself. All the other fish are pretty mellow but the clowns can get aggressive if you try to get in their corner of the tank. Maybe he got scared of them.
Thanks. I feel better.
