Growth on face #1
Can anyone tell me what this growth is on the face of one of my Harlequin Rasbora please, and what I need to do to treat it? I also have a colony of red cherry shrimp in the same tank so any treatment needs to be copper free. Thanks for any advice.

Re: Growth on face #2
I'm not seeing anything untoward other than the fish's nostrils/nares.
Water quality consistently at 0 ammonia, 0 nitrite and 20 nitrates ought to help most issues resolve. You may also find either API Pimafix or API Melafix helpful, depending on what it is that you're seeing.

Re: Growth on face #3
Hi and thanks for your reply. I've circled the area of concern in the attached photo. It looks like a raised white lump.
