my cory is sick

my has alot over bubbles on it and it's no moving as much as the other fish! please help do u think it ich?

More information please, water parameters, tank size, etc....

a picture would be helpful too....

my tank is 55 gallons! the water is 7ph, the temp is 78 degrees, the water is hard but thats because i live in south georgia. i have two raphael striped catfish, two mollys and two paired angel fish! the tank just went though an algae outbreak! i can take pics with the phone but they suck!

We need your ammonia, nitrites and nitrates. And a good picture will be better then trying to explain it to us.
