Torn or ragged fins in Bala Sharks are often due to stress, aggression, or poor water quality. These issues can be serious if not addressed promptly, potentially leading to further health problems. As an intermediate care fish, Bala Sharks require a large tank and specific water parameters to thrive. Owners should first ensure a stress-free environment and proper tank conditions before seeking further treatment.
