I am not sure if Blade has an infection. When I bought him he had a black edging to his tail and his tail was nice and smooth. I only have a few pics from when I bought him and this one is not great
However over the last week it has become ragged and some of it looks a bit transparent. He was in with neons which I have removed today and have carried out a 20% water change. Here he is today getting some excercise with a mirror which shows his tail as it is now
My local shop has suggested another 20% water change on Wednesday and Friday and then I will take a sample in to be tested if there is no improvement. They have suggested treating with salt if there is no improvement just to be on the safe side
He is still very healthy and active and eating well so not sure if it is nibbling or an infection? Any thoughts
