Don't know what lumps are

[senecasmoker]

I have a roughly 16in solid white gin rin butterfly koi.. as I was feeding today I noticed it has 2 small (that I saw, they are very skiddish right now due to removing 3 of my larger koi and then adding in 4 small ones & a crate for them to hide in, then we had a cold snap) on its side, I didn't get a great view but it was hard for me to see because the lumps blend with my fish other than being shiny i could only see them from above.. how can I tell carp pox on a white koi? Does anyone else know what it may be? When it came to feeding it acted as normal as always, and the lumps don't have any color to them but one is a bit larger than the other.. ill try to get a picture tomorrow
