Answer
I recommend a CAT Scan.

There has to be something wrong with your brain if you are putting 2 goldfish and a pleco in a 10g tank.

1) Goldfish need 30g tank, minimum
2) Plecos need 150g tank minimum, they grow over a foot long.
3) Goldfish are coldwater, plecos are tropical, NEVER mix coldwater and tropical fish

Now, he has body fungus. Do a 75% water change, then go to the store and buy a body fungus medication. Follow the instructions.

It might not work though, fungus is caused by very poor water quality and owner stupidity. Sorry if thats not what you like to hear, but if your fish gets that amount of body fungus you should really reconsider keeping fish. Or at least spend a good few hours doing some research so you can get even the simplest idea of what you are doing.
