hi there first post here so let me know if i miss anything

i noticed a large (relative to body) lump of some kind on of my shubumkins , the fish appears to be fine otherwise no change in how it swims or in its appitite and it doesnt shy from the other fish .

there doesnt appear to be any thing else wrong with the fish , any advise welcome as this is a new one on me :/
sorry about the blur its quick when it want to be.
