No, ich is an infection and appears in multiple white dots. Like pimples almost. This pic looks like he rubbed his scales off on an ornament or got caught under something. Check everything in the tank to make sure he didn't wiggle under something. When I upgraded my tank Bowser wedged himself behind the filter bc he didn't like the current.. He got rubbed.
Clean water and fix the decoration should cure this in no time. If, however, you find it does not clear up or start improving or you notice his behaviour is "off" you can start a treatment by which we can help you.
