Yeah, that sure does look like ich alright. Raise the temp to about 86 very slowly.. 2 degrees increase every few hours. After that, purchase some ich attack by kordon and use when the ich appears to have gone through it's life cycle and drop off of the fish, and then start treating immediately every day and follow the water change instructions on the bottle. This method worked for me. Best of luck.
