What is this on my betta?

[TheBettaKeeper]

When I was feeding my betta yesterday, I noticed a strange white lump of some sort on his dorsal fin. He doesn't have any other lumps or spots like this, and it is quite raised off the surface of his fin. Can anyone help identify this?

Here’s the link to a video of my betta:

(Sorry if it’s a little grainy)

A clearly focused still shot would allow zooming in to try & see more details. It’s next to impossible to get a good look at anything in a video of swimming fish.

Any idea how long it’s been there?

I’ll add a picture, sorry, it was just taking a while to get a focused shot. I’m not completely sure how long it’s been there, but I didn’t notice it on Thursday, Friday was the first time I took notice of it.

Ok. So it may have been there longer than it seems - we don’t always notice small changes.

Yes, especially since the portion of his fin that it is on is almost the same shade of white, even if the picture doesn’t do it justice. Speaking about the picture, here you
Does the picture I attached work, or do you need another angle?
