I've always had a Betta fish with no problems, but today I noticed a growth on it. My camera wasn't working, so I had to resort to my cell phone camera. I know it's not much, but it's some visual reference. One on side it looks like the fin is just enlarged, except for the tip of the growth which is white. On the other side it is red and white. The fish is by itself (and it is my only fish), so it didn't get it from another fish.
My apologies for such a horrible picture. The tank is a little dirty too.
Any help is appreciated,
