Colt Coral Not standing up

[Sean]

Hey guys, I just got a colt coral i placed him in my tank last night. He has grown back out to roughly the size he was at the store but he isn't standing up instead hanging from the side. At first I thought it was because I had him on the sand bed, but moving him up in the tank has not corrected the issue. I know its still very early as he has not been in there 24 hours.. is this normal?
