My Clownfish and a Colt Coral

[jeemann99]

Just about 2 days ago one of my Ocellaris Clowns hosted a Colt Coral. The other one just circles it from time to time, but stays pretty close to the other one hosting the colt coral. My question is that the one hosting in the colt coral just seems to lay there inside of the colt without moving very much like sleeping. Is this normal behavior? Is it sick? I only had the clowns for 2 weeks. Also, is my Colt Coral in danger from being hosted?

thanks in advance
