You most likely have fin rot or something going on due to poor water quality, which is generally the culprit of 99% of tank problems. I would recommend starting with partial water changes weekly and see if he improves or if it continues to get worse. If it does then it could be some sort of infection, and need some anti-fungal or other treatment depending on what the symptoms are.
Check back in and if you can link to any pics that would be great.
