The clownfish look healthy, but the tangs breathing rate has increased and there seems to be a water mark looking thing on one of the clownfishes head but other than that everything seems fine.
Not sure what you are describing about the clownfish, can you post a pic?
An increase in the tang’s respiration rate is more serious than the slightly elevated, but steady rate.
Ich won’t cause rapid breathing, not with a light infection. However, the fish isn’t stable, so I’d hold off moving it.
