My 5” Majestic Angel is acting and eating normally, but I noticed this white crusty looking patch just on one side of his body as shown in the attached picture/video. Does anyone know what this is, what could have caused it and the best course of action to treat it before it gets worse. I first noticed the latch a few days ago.
