I'm new here!

I'm not new entirely to marine fish keeping. I used to have a marine/reef tank 4 or so years ago but I was a cowboy and it was a bit of a mess! Used tap water from the start, didn't have much money back then etc. I still had limited success with some soft corals and a yellow tang and clownfish surprisingly.

Anyway I've just started again. Cycled a new tank for 3 weeks using some very very cured live rock another reef keeper was selling. It's full of life. I have been testing the water every day for ammonia, nitrite, nitrate, phosphate, calcium, kH, PH and magnesium. I had a small spike a week and a half ago and now ammonia and nitrite are zero and nitrate about 6ppm. Done a waterchange since. Everything else is good.

So I just got two clownfish. They seem fine except one has a white lump on its face. I did not notice this in the shop but it was def there before it got into my tank because I first noticed it when I was floating the bag.

I've taken pictures. Can I upload them here? Anyone any idea how serious this is? Should I return the fish? The other one has no marks or indication of anything wrong. Both are behaving normally.

The photos are sideways. It's the bottom photo and the fish in the right. They aren't great pictures but umyiu can see it's white and huge like a wart!

No idea what it is but if I'd seen it in the bag it would have been back to the shop. I would still take it back even though its now in the tank.

I've looked at it again this morning and I'm starting to think it's a wound.

IMO it could be a small lymphocyst picked up from a small wound , it should clear on its own given good water conditions and diet . But certainly keep an eye on it just incase.
