yes! bring it inside!
my mom has one. she got a wire basket and lined it with moss and planted the fern in there. in summer, she hangs it outside from the branches of out maple
tree. when it gets cold, she brings it inside and hangs it underneath the skylight in the kitchen. its very happy so far, and even has babies now.
my mom also soaks it in the tub when it needs watered. i don't know if it needs fertilizer though. the plastic bag is under it so the water doesnt leak all over the place.
here are some pictures of it i just took
