Clown with white "fuzz" on chin?

[leevh]

Hi all, wondering if anyone can help give diagnosis ideas (pls see photos attached). He's a small new clown and we've had him for about 3 weeks and he's had a white lip for most of it. He's had that piece of frogspawn with him in quarantine since day one and at first I thought he hurt his lip on the coral. I've been feeding food with focus, metroplex and kanaplex for two weeks and it still looks mostly the same. Though this is the worst it has looked today. He eats, swims quite energetically otherwise.

Any thoughts? If it were brook, wouldn't it have consumed him by now?

Thanks for any help

It could be a fungal infection.

Thanks for the reply blaxsun! I have both paraguard and kanaplex, any thoughts on which I should try first?

thanks again
