Fins on my Betta~

Is this how the fin should look?

It looks like it's gotten torn a little. Might be from a plant or decoration in the tank or he might have blown it while flareing. It should heal on it's own. Just be sure to keep the water clean so it doesn't get infected. You might try testing the plants and decor. Run some nylons/panyhose over them. If they snag, they can damage your boys fins.
