Don't know lol could just be a goofball. During the day everything is normal and it eats well so that rules out lateral line problems or just about anything else I can think of that would cause it. I don't think it's physical as my clown sometimes adopts very unnatural sleeping positions as well. I'll try to get a picture of it tonight, usually by 11:30 it's out cold. I also thought it was odd as I remember reading another member thinking they never slept as it was active day and night.How weird. The tank it came from is right next to my desk in my bedroom so I'm surprised. I either never noticed or it's new behavior?
