I've had my betta for almost a year and he has a spot on his side where his scales had fallen off, and now one starting on the opposite side I got melafix and pimafix to treat him, as well as salt. This morning he had the cotton wool growing in the wound. He also has some white spots that appeared.
He has been in this tank for about 6 months and its a three or five gallon tank and the water probably isn't the ideal condition but this is the first problem I've ever had with a fish. He shares the tank with a snail but I think it died.
I have looked at many sites to try to help him and they all say something different.
What is the best way to treat him.
Any help would be appreciated.
