Strange Spot on Flowerhorn

[dr_girlfriend]

Hello all. I'm new to this site. I needed some opinions on a white spot on my flowerhorn. Its slightly raised, with rough edges but no swelling or redness surrounding it. It started probably a month ago very small. It is located on her lower right side, above her pectoral fin.
At first I thought it was an injury, but it has gotten slightly bigger. Its probably about the size of a peppercorn. All water parameters are normal and she is alone. She is eating normally and is behaviorally fine, It just concerns me as to what this could be.
