Hiding fish

[duff]

I have had a Kole tang for about six months. He was happy, active and got along well with the other fish until just recently when he became very reclusive. Now he just hides all day and only comes out sometimes to eat. The water perameters are all good. There are 2 ocelaris clowns, a melon b/f and a 3 inch juv. emperor in the tank.

Are anyfish being aggressive to it? Does it show any signs of disease? For a wile once my niger triggerfish for some reason stayed in it's cave almost all the time, but eventually he came out, if no other fish are harrassing it, or if it's not sick, just give it some time, and make sure it's stress free. Good luck
