What could be causing my molly fish to have a bulging eye?

Answer by  sharonl (250)

A bacterial infection called Pop-eye is where the eye fills with fluid. It is usually caused by poor water quality. Doing regular partial water changes, adding aquarium salt, and a bacterial medicine such as maracyn will help it.
