Who Gives A Fish Forums

I'd really appreciate some help here.
My sister's clownfish has these weird spots that just won't go away - it's been a couple of weeks now. Her smaller clownfish had them too, but they cleared up, whereas this one's still got them. The good news is, he's acting fine and eating normally, so that's a plus, thanks.

Hey,
Can you please share some clear photos of the clownfish under normal lighting?

Besides taking the pictures under normal white light (not blue), how long has your sister had the clownfish, and how long did the smaller one have those spots for?

What's the water change schedule like? We'll need to know the pH, ammonia, nitrite, nitrate, GH, salinity - the whole works.

It's possible it's just excess mucus from poor water quality, or it could be something like brooklynella, an external protozoan parasite.

Can you please provide a pic under regular white light?
