These are mucus cones often from a skin irritation and at times are mixed in with ich and Often you will notice other occupants show no signs but recommended is to remove all fish and treat them as well using coppersafe or copper power for a full 30 days at 2.25ppm which they respond to well and add an air stone and monitor copper level with a reliable Copper Test kit such as Hanna Brand- No API brand. Also monitor Ammonia levels while in quarantine with a reliable test kit and add aeration during treatment using an air stone.

Those large, discolored areas are stress related and should fade. My Hippo gets them all the time. He probably has them because Vette is absolutely correct that there are Mucus Cones appearing as those white raised dots. Most likely Ich and unfortunately your whole Tank will be infected and will have to be Fallowed with the Fish removed. If it's a FOWLR you could treat it in Tank.
