It's possible he has finrot, got into a fight, or it got torn on a sharp edge. Be sure to keep his water clean, and fresh. Avoid decorations with sharp edges. Often times pet store bettas live in such poor water conditions that they get fin rot. 95% of the time they recover once they are properly kept. If the fins continue to shrink you need to add melafix/bettafix, or an antibiotic.

I have one that was the same way, it was still really pretty and lived for about 5 years I think. So it should be fine.
