My one neon had a swollen section at the end of his body for awhile and he has been fine for months but today I noticed it looks like there is a zit on it. He swims fine and no other fish in the tank have/had it. Any idea what it is? treatment?:confused:
 
Could it be the dreaded the NT disease,if it is,remove all the neons or the affected ones.There is no cure for this disease.
 
No other white spots just a fair sized yellow/white zit head looking thing and a little swelling on the other side of the tail. He has always been swollen for as long as I can remember. He swims and eats fine, no others have any spots or swelling.
 
No it doesn't. NTD presents as a loss of colour, not as a raised spot.

Having said that, I'm not sure what it is. Could be a tumour? An encysted parasite?
