[ghost knife]

Hi all. Please can I have some advice on to what the white lump is on my angels fin and what needs to be done to treat it please??

Which fin are we looking at?

The small fin on his side

If you mean the lump where the fin joins the body, then it looks mormal to me. It is the pectoral muscle.

Any chance of a closer photo?
