So, have had a Mccosker in QT for a few weeks now. Has been through 1 prazipro tx and has been eating well since almost day one in QT. I have noticed him spending time at the surface quite a bit. Added more circulation and airstone, however didnt really seam to make a difference. Tonight when i went down to feed I realized things had gotten much worse and he didnt have any interest in eating. He has an open mouth, with almost a fungal looking rot going on. Also the underside of his jaw looks slightly red. Here is a video:
