We have 3 P.J. Cardinals, all of them have ragged looking tail fins, and 2 of them have a single white spot on the center of their left eyes, however their eyes don't appear cloucdy. I have noticed this for a while. One of them is getting worse (the whole tail fin is almost gone), the other 2 appear to be getting better. There is one cardinal that has a longer tip on it's 2nd dorsal fin; this one bullies the other 2 cardinals around, so maybe it's aggression?

Sounds like they are sick, but what other tank mates are there?

It could be either or both. If one is nipping the others, and the your water parameters aren't up to snuff, then whatever injuries they have could be getting aggravated.

Could be one or both of the clowns. I'd spend a little extra time observing.
As an aside, one thing I've learned from experience: You can't always rely on test kits to tell you the overall quality of your water. You can literally have a tankful of algae and get "0" readings on nitrates and phosphates. Why? because the algae is using them up as fast as they appear.
