First welcome to the forum 
It looks like ick but its hard to tel.
How long has the tank been set up?
What is your tank size?
What is your temperature?
What is your PH and hardness of the water?
What filter are you using?
Are there other fish in the tank, and how many?
Was the tank cycled?
Sorry for all the questions, but it will help us help you
