yes, before he got sick, his lips are about 1/3 the thickness of now, the lips are swollen.Is that duck lips? I'm looking at my Synspilum right now, and his lips are about 1/3 the thickness of yours. Hard to really know from a picture, and not seeing the fish before he got sick.....but I'd guess duck lips. Columnaris bacteria infection. Very lethal.
If it's columnaris, you need a combination of Nitrofurazone and Kanamycin. It doesn't usually respond real well to treatment.
what is the "ragin_cajun" exactly?Sounds like ducklips, there is no quick definitive treatment. The infection is normally fatal to the fish, if caught early enough the treatment ragin_cajun suggested might help
Oooops sorry i don't attention it's the profile name of David.
I can't find Nitrofurazone and Kanamycin, but use powerful antibiotic, Cfalexin 500Hope it works out for you
