Prazi & Metro

[alans az]

Is it ok to medicate with prazi and metro at the same time?
I have fish in my tank showing seperate signs. One is breathing a little hard and is a little dark. Flukes maybe?
One other looks fine color wise, but does not seem to be eating.
Water parameters are good and the other fish all seem fine.

I like formalin for flukes. I would do the metro first. The increased heat my stir up the hunger too.
