[cells]

I have 2 domino damsels for 2 weeks. one of them developed a white growth at the buttom of its chin area 2 days ago. this morning it stopped eating. yesterday it is still eating like a pig.
can someone tell me what is wrong with it? and how should I treat it?
Thanks.

Could be severla things.. From a parasite to a bruise from hitting the glass.
Try this in the disease forum, someone over there might have more answers with a better description.

I brought it to a LFS, and the expert said that it is bitten by the other damsel. He switched the injured damsel for me, and ask me to get a third one. He said for damsels, I should keep a minimum of 3. So now I have 3 damsels in the tank.

Well, damsels can be pretty aggressive, with the larger usually being the most aggressive. It is not unusal for the largest to kill off or harrass the smaller damsels. What type of damsels are they?
So, you no longer have the sick fish?

I have domino damsel.
Yester I switch the sick one with a healthy one, and got a passive big one. but the passive big one is not eating.
maybe why it is passive is because it is sick (not eating).
I tried to target feed it with frozen shrimps but it is not eating either. I'll try again later.

Give some info about your tank: size, water readings, other fish? etc.
