I can't exactly tell what's wrong with my betta, Gideon. I've had him for almost one year. Basically, he has a significant amount of tearing on his fins. However, it just gets worse SLOWLY. Very slowly. From my understanding, if it were fin rot, my fish would likely be dead (or at least have no fins) by now.
The progression of this was so slow that I didn't even realize his fins were much different until I looked at a photo from August (2012), last week and realized what a significant difference there is in his fins. He has white blotches (not cottony, or ich-like at all) on his fins. his body looks the same as it always has. His fins also have large tears, though he only has silk pants, no decor with sharp edges, and I've never seen signs of tail biting.
Here's the basic info on him/his tank:

Symptoms and Treatment:
How has your betta fish's appearance changed?
His fins appear really torn. Ragged and curled at the edges. Some white blotches on the fins. No change in his scales/body.
How has your betta fish's behavior changed?
He is lethargic. Always laying on the bottom, unless it is feeding time. When he sees me coming to feed him, he'll swim around. He swims for a few minutes after, and then goes back to the bottom, resting on/near decor.
When did you start noticing the symptoms?
Tears in fins progressed VERY slowly over a period of months. Lethargy has only started in the last 2 weeks.

No. However, I own Maracyn and Maracyn 2, but I have not treated him with it yet.
Does your fish have any history of being ill?
He had mild fin rot and swim bladder disease when I bought him, which was taken care of with clean water, very quickly.
How old is your fish (approximately)?
At least 1 year old.
