Clown fish, worried

[saintsfan]

I have had my clown fish for 3 1/2 weeks now and I am worried. Usually when it is feeding time, my clown would come out and eat like crazy. For the past 3days he has not come out to feed and is staying in his comfort area. Can someone :help:

Any other fish in the tank that may be picking on him?

I have two damsels but they leave him alone. My clown will let the smaller damsel in his area but he chases the bigger one out.

Hmm, is he breathing hard, mucousy, also stage a night vigil, to watch them for signs of aggresion at night.

my clown has passed away. Believe when my husband moved the LS around, everything in the sand was (what it contain) my have killed my clown due to high volumes. We were told by the fish store to do this to keep down the algea (brown) but since then we spoke to a trust hobbiest in town and the threads here and was advised not to do this due to the LS loosing some things needed and the high changes in the water could affect clown,,,found out too late.
