| yes, it can go away on its own.
while i cant pretend to totally understand this, from what i know they fish doesn't even have to be exposed to an infected fish to get ick.
i guess its on of those things that if you were to have a tank raised fish, that has been kept away from all other fish, it could still develop ick, if put into a stressful situation.
again, i dont fully understand this, so i cant say much more about it.
