Clark Gable has been in QT for over a week with 100% daily water changes and 1/4 teaspoon of AQ salt, what I thought was improvement is quickly becoming a worry. I have noticed that some of his tail is growing back and as I watch him carefully everyday I noticed 2 days ago a pink circle as he is a marble I didn't think anything of it but now his fin has split in half so I am assuming the pink circle was blood. I don't know whether to continue with the AQ salt or go and buy some medication from the LFS, I really was hoping it wasn't fin rot but looks that way, I would take a picture but as he is cellophane the camera doesn't pic up on his tail very well.
