Clownfish Lymphocystis or Parasite?

[sapphireminer]

Hi all—woke up this morning to my larger (2.5”) black ocellaris with a white bump under his mouth. Has been eating normally. Normal behavior. Normal poops. She’s only been in for a week. Tank is a little over two months old, they are the only fish inhabitants. There is a BTA doing well, but they don’t have a relationship yet, sadly…

Does this seem like a lymphocystis or a parasite or something else?

Can you get more pictures? It could be but not 100% sure. Best to keep water quality good and if fish keeps eating, pooping, breathing, and acting normal; then don't do anything else but observe for now.

Don't mind the white dots, they aren't on the fish, they are a booming pod population on the glass from AlgaeBarn.

Unlikely to be Lymphocytis - clowns don’t get that very often, and it just doesn’t look like it.
My guess it is a bump from hitting something….could even have gotten stung trying to enter the BTA. In the absence of other symptoms, I would just watch it closely for now.
