Stress

[KrazyKuch]

Is their anyway to make a fish less stressed in your aquarium other then lights off?

I have My new Blonde Naso tang who is haveing a real hard time in my tank, the first night he was fine hiding in a cave but this morning he was laying on the sand breathing very hard, and I thought I was gonna lose him. Since I got home tonight I saw that he had left his cave and went to another cave...still breathing hard and resiting on the rocks, and now he has gone somewere where I can't see him so I can't tell how he is doing..


Is their anything I can do to help him through this, I don't want to lose him cause I have been waiting for a Naso for quite some time now and I don't see them come in very often!
