Is this damage or disease

Sorry for the bad photos but is this damage to my yellow assessor fin or something else looks like a lump on his front fin just one side

Welcome to Reef2Reef!

Sorry, the pictures aren’t clear enough to see. Does the fish have any other symptoms? What other fish are in with it, any of them a possible culprit for doing damage? How long have you had the fish? New basslets sometimes get a minor viral infection called lymphocystis.

He seems fine swimming and eating well it doesn't seem to worries him I only got him a few days ago and he had a fair travel to get here so I though maybe got bumped around

Will need side pics of the fish opposed to top down to clearly see anything you are referring to
