Rainbowfish With A Problem?

This is one of my Blue Rainbowfish. I noticed he had this mark on his side yesterday. It looks like a spot and is slightly raised from the surface of his body (if that makes sense?). Just wondered if anyone out there might know what it was?
He shares his tank with Boesmani and Dwarf Neon Rainbows, Polka Dot Loach, Angelfish, Bristlenose, Corys, Kuhlis and Black Ruby Barbs. And an Oto!!

Many thanks in advance.

Hi,

Yes he seems fine apart from the small mark/lump. I am hoping it is just a bite/scratch and not anything more sinister?

It doesn't look like cotton wool no.

Thanks.

does he try to rub against anything like its irritating him? or is he darting about or swimming differently?

Maybe the lump is a tumor?
