It may be fin rot. This can develop due to poor water quality or infection. Use a home test kit to test chemistry. You can also submit a water sample for testing. Most pet stores or aquarists will do this for free or for a nominal fee. Correct any imbalances via partial water changes and/or chemical treatment. Adjust water flow to decrease current strength to aid in healing. A broad spectrum antibiotic, such as minocycline or erythromycin, can be used to treat infection. You can buy one at most pet stores. Follow label directions.
