Has Anyone Ever Seen Anything Like This?

Hi,
First post here, so be gentle...

We've had this fish, whom we rescued from a wedding centerpiece, about two years. He lives in a 2 gallon glass bowl, with polished glass stones, no gravel, and soft, non abrasive rubber plants. We change his water completely and wash the stones/plants once a week. Water is tap water left standing in gallon jugs one week. Heater set at 77deg. He eats Betta Bites, which we hand feed him one at a time until he stops eating, so nothing is left to settle to the bottom. At this point, he's still swimming, eating, but rests on the bottom more than usual (no wonder...).

Water readings as follows, water was changed Sunday:
pH=7.0
Alkalinity=90
Hardness=120
NO2=0
NO3=0
Ammonia= Not detectable

We only noticed a couple of days ago. I know it looks terrible, not sure how we didn't notice, assuming it's been there much longer, except that his tank is in a very dimly lit area. We're very, very fond of our Betta, and want to help him. Any experience or advice greatly appreciated. Thanks so much. This is the top of his tail, at the base:

Finrot??

I would say finrot too.

I couldnt understand from your post how much you feed him, they should have no more than 6 pellets a day and 1 day of the week none atall to let their systems clear out.

He looks like a beautiful colour!

What do you use in your filter? There should be some nitrate in your water?

I thought finrot, but not sure. Out the door to drive an hour to pick up some Kanaplex. He eats very little, always has. 6 pellets a day would be a lot. We always thought that was odd, but I guess its normal. You can't tell from the picture, but he's a gorgeous little thing, with perfect (until now...) fins & tail, wafting through his little world like a proud man-o-war. This is really sad. Hope the Kanplex helps him.

I'll be back in a couple of hours, or more if the traffic is as bad as I expect...

My betta had sparkly fine powder looking stuff on his fins like that, which turned out to be velvet. I treated him with dark light and aquarisol. I don't know if the sparkly part is what you're concerned about or if that's just the normal coloring of your little guy though.
