This is my 10 year old maroon clown. She has a lesion, almost hole in her side and fin rot. Dont want to treat without knowing what is. Time is of the essence, thankyou for any help. Below is a video, hope it helps.

That infection was pretty bad. I've lost fish in the 10-15 year old range, so I know how you feel right now...
You also need to keep a close eye on the male (and all your other fish as well.) I have a feeling there is a parasite lurking in your tank which started all of this.
