Hi,
This morning I have noticed a white lump on my Gouarmi's pectoral(?) fin, I was hoping you guys could help me identify the problem and suggest some medication (if required). I have a attached a picture I managed to take of it with my mobile phone (quality not great).
One thing to note is that my Nitrate reading is very high, 80ppm, this is due to my tap water itself having a Nitrate reading of 80ppm, I have another thread about this asking about advice. Could this be the cause?
