Concerned about Discus Health

[Cameronb_01]

Hi,

About three months ago one of my discus accumulated so many little black spots that he effectively half turned black. Apart from the visual deformation there were no changes to his appetite or behaviour around the tank, consequently I put the change down to a very severe and sudden case of peppering. However, on further inspection I now notice that a segment of his fins right at the back appear to have been gnawed off- I have been looking out for signs of bullying in the tank and have not noticed anything imparticular focused on the fish in question.

Should I be concerned? Does anyone know why this might have come about?

Thanks in advance.

Best wishes,

Cameron

i would do some major water changes over the next week and see if it starts to clear up.....maybe 40-50% every day

thanks for your reply mikey,
do you mean that the blackening / missing fin issue is reversible?
