BigA - Thanks for the info. Now I was able to find some more info about it. However, it seems like there is no treatment for this condition. I doesn't seem to disturb the fish too much in term of eating, however he became less active lately. It is a beautiful fish. Too bad he had to get this lumpy nose thingy.
Has any one else encoutered this? Did you manage to treat it somehow?
Dsaundry - what is that medication against? I don't like giving medication to my fish in general..and here I don't even know the name of this "disease"...Not the best idea to throw in meds
