fin rot is brought about by poor water conditions allowing the build up of bad bacteria in the water and gravel. These bacteria get into the fins and cause them to split and deteriorate.
Quite often doing daily partial water changes and gravel cleans for a week will make a difference. If it doesn't make any difference or gets worse after a few water changes then you will need to treat the fish with something.
