i have 4 axies, 2 of which got what i figure is Columnaris, I used a methane blue solution in the water which seemed to work really fast as all the fungus dissapeared overnight. They both seemed to come right except the ends of BOTH their tails have now "fallen" off. They have sort of more like "rotted" off as the blood vessels retracted (i could see this clearly on the white axie) Only about 1.5cm of the white axies tail fell off and he now seems pretty good now, but my black axie it was more like HALF his tail. It went sorta fuzzy and then eventually disentigrated away in the water. Looks ok i guess except about 2cm of his "spine" or tailbone is dangling out the end??? he is still eating and looks perky...what the hell do i do??? im abit worried:sad:
