Clownfish has white slime! Help!

[tankshark]

Hi, please help, any advice is appreciated!
My sisters clownfish has these “spots” and has has them for a couple of weeks. Her smaller clown had them and now they’re gone, but this one is still “infected”. He has been acting fine and eating like normal, thanks in advance.

Hey and
Can you please provide regular light pictures ?

Besides providing pictures under normal white light (not blue), how long have you had the fish for, and how long was the smaller fish covered in the white stuff for?

How often do you do water changes?
What is the pH, ammonia, nitrite, nitrate, GH, salinity, etc?

It could be excess mucous caused by poor water, or brooklynella (an external protozoan parasite.
