Was doing my hourly checkup on my fish and noticed my pygmy angel has some weird discoloration on one side. I've attached a few pics, one if which is the other side which looks normal. The picture in which the fish is pointing to the left is the side I am concerned about I apologize if they are not the best pics. To my eye it looks like he has a patch of faded coloration... Any ideas on what it could be? Thanks in advance!!
