Open sore treatment

[clm08k]

has the open sore improved?

Would definitely try to improve water quality first if possible. I've dabbed a poly with iodine before, but it seemed to be quite stressful for the fish.

So busy these past few days, haven't had a chance to write an update. The sore is almost fully healed now. Thank you all for your advice!
I did dab it with just a touch of iodine. Didn't seem to hurt my poly.
