The rash is slightly raised bi-lateral blotchy pink/peachy area starting around and encompassing the area around the white tail spike and continuing, unevenly up the the sides to about mid body. It unevenly follows the lateral line, but is more highly concentrated around the tail area. The left side of the body has slightly less rash area than right. The yellow tang being about 5" from nose to tail, the rash on the left side would (total area) be less then a quartercoin in size, but (total area) 1 1/2 quarters (coin) total area on right. The areas are not round like coins, they are distinct blotchy areas, varying in size and extending up/down. The borders are exact and it appears to be SLIGHTLY raised, but VERY SLIGHT. The largest area being tail portion of right side with the area being the actual size of a dime. There is no puffiness or swelling anywhere else on the body and she is behaving and eating fine.
