white dots

[jassz]

So these white spots are not a sign of overfeeding? I read somewhere that was the case, but I find I have to leave a little food in the tank as I have one timid eater that nibble once everyone else is done.

I looked at these white dots with a magnifying glass, and they look like a rolled up worm. Do they eventually turn in to something else?

Thanks,
