That's definately not ich, like someone before said it looks like he rubbed something - you'll have to watch that close becasue a fungus could have taken over the wound. My fiance had big problems with fungus and those tablets they sell at the store never seemed to get it really. So we moved to Prima Fin and Mela Fix. Can't remeber which one does what but I know in addition to the medicine they have aloe vera to help the wound heal. Your tank may look cloudy, but those helped fix up our fish which we thought we might lose. You'll know ich if you see it - it will be distinctive white dots. Like your fish got into a mini shaving cream fight and got splattered with fine droplets. Hope your fish gets better.
