After some advice please. I have a Blackmoor that developed two which 'spots that look to have developed into tumours. There was one on the head of the fish which eventually dropped off/healed but the one near the tail is getting bigger and is looking quite sore. Doesn't appear to have affected the fish very much but I wanted to know if there is any treatment I could give? I've read up a little and understand these could be harmless but never really sure I'm reading up about the right thing. Any help would be greatly appreciated. P. S you will notice the blackmoor has almost completely changed colour, not sure if that is normal or not?
Thanks in advance
