My betta appears to have a case of fin biting, and I'm treating him with small doses of aquarium salt. Right now I have a sword plant in his 2-gallon filtered tank, but it started dying as soon as I started him on the aquarium salt and I'm anticipating having to replace it soon. Does anyone know of any plants that would be resistant to aquarium salt and less likely to die in a tank with regular doses of it? I don't know if this fin biting will go away anytime soon so I'd like a plant that can handle a bit of salt for possibly an extended period of time.
