Clown fish have not eatten in 4 days

[websurfer]

About 8 days ago i introduced a pair of pink skunk clowns with my all ready existing false percs. The first few days the percs did nothing the 3rd day they would look for them and run them to the other side of the tank the 5th day the percs stopped eating and just lay on there Anemone and do not move.

They look like that are breathing very slow the color is the same no itching what so ever.
Any ideas the other clowns are eating fine but when they first came in it took a few days.

I have not had a chance to get a water reading.

Tank specs are 60gallon tank been setup for all most 2 years clowns have been in it pretty much since day one.

All other fish are eating with no issues. Today it loooks like the fin are falling apart as they are not full anymore it looks like something could be eating the fins off?

I have read that i need Melafix
