Cotton Growth on Clown (Pictures)

[petebsbll]

Hi All,

My Clownfish of 5 years has some cotton growth below his lower lip. I first noticed it yesterday. He's been mated with another clown for years. They are both in an established 65 gallon aquarium. All tank parameters are fine, so I won't waste your time (or mine).

To be honest, I haven't had to play fish doctor much over the last 5 years with this build, so I'm rusty. I'm guessing this is a bacterial infection. The water quality is fine, so possibly an abrasion caused it? Open to suggestions on a diagnosis and also what to treat with. I appreciate it!

Please refer to the photos. Thanks again!

Could just be Lympho: https://humble.fish/Lymphocystis/

But if he got "mouthy" with a stinging LPS coral, or zoas/palys there is a chance it might be infected. Best treatment for that would be Kanaplex + Metroplex in a QT.

Cotton is ususlly fungus growth in freshwater. I am only 7 months in saltwater. But 20 years in fresh says fungus to me. I dunno if thats possible in salt though.


For fresh water id be using malachite green.victoria green

Fungus is very rare in SW fish.
