I think CK has columnaris. I came upstairs this morning to find he has a wooly growth on his ventral fin, and he’s flashing a bit. Along with his lethargy, dull colors, and lack of appetit, I think it’s an appropriate diagnosis. Before I left for my trip, I did add new plants to the tank, so the bacteria could have hitched a ride that way, which would explain his illness despite a lack of poor water quality.
I have some leftover kanaplex that I’m planning on dosing him with. Unfortunately, I don’t have a place to quarantine him and will have to does the whole tank. I seem to recall the plants being find the last time, but I do have snails and some shrimp that I’m worried about.
^the pictures from two days ago, when he seemed to be doing a little better. Since I’ve been back he would sort of peak and valley in terms of recovery. I even started to wonder if he was just getting old and I was over reacting. I recently looked at his old picture and his raggedness and skeletal frame are much more apparent.
