No. Not normal. He is a fish and needs to be swimming. Unfortunately, I would guess he is not going to make it till morning. Five minutes of laying on the sand is not a good sign at all.
I am not sure what you can do at this point other than perhaps a water change, but that will have minimal if any effect on a fish. have you tested your water for ammonia or nitrite/etc.? If he was healthy to begin with, I second Chad's questions. Are there any other signs of stress in the tank, or is it isolated to this fish? How long was he at the LFS or wherever you got him? Have you added or changed anything else recently? How old is the tank? I do not want to judge by the number of posts or jump to conclusions--just want more info--but it seems you are new here: is the tank new as well? How did it cycle and how long ago? The pic looks like an elegance--was the clown staying in that spot/hosting-like behavior up until now? What other inhabitants do you have?
