Clownfish - white mouth
 

Hello,

I've noticed yesterday morning under night light my female clown fish had what looked to be cotton around her mouth.

It looked to disappear slightly throughout the day but have noticed she doesnt completely close her mouth.

She is still eating like a champion.

My male clown 🤡 is looking normal and all other fish/ inverts are well.

Looking to see if anyone has had something similar and a little bit of advice on treatment.

Ive tried to get the best picture i can.

I should have also mentioned it comes back over night and looks worst first thing in the morning.
