Wart/blister On My Betta

[helwergles]

Hey,

I've been keeping a betta for almost 2 months. I was out for 2 days, and yesterday, when I came home, I noticed a kind of a warp/blister on my betta's dorsal fin.

Does anybody know what it is? Is it an illness?

He's eating and swimming ok.

He lives in a 5 gallon tank, AquaClear20 filter, thermostat, chemical tests are ok...
