Can a betta regrow an entire missing fin? I saw a female betta at the store who was in a community tank and her entire left fin was bitten off.

Given the right tank conditions and diet, she may regrow all or part of her fin. Maintain pristine water quality via filtration and regular partial water changes. Offer a healthy diet and minimize stress. It can take weeks to months, so be patient.
