Yeah, it's actually looking up through the anemone toward the surface of the tank. I'd just fed it a big shrimp and it folded over on itself to injest it. As it started to open back up, it was like this for 2 or 3 minutes. I wish I would've increased my shutter speed a bit to try and freeze the action a bit more, but I think I would've lost some of that glow if I had.
