One of the easiest ferns to keep alive indoors, which is not a crowded field. The fronds are narrow ribbons rather than the usual lace, often with a silver stripe down the centre, and the plant stays small enough for a shelf or a bathroom windowsill. It takes lower light than most ferns and forgives more, provided the one thing it cannot forgive does not happen: the compost drying out completely. Keep it lightly moist, raise the humidity if the room is heated, and keep it out of direct sun. When it fills its pot, tip it out in spring and pull the clump into two or three pieces, each with roots and fronds, and pot them separately.

Ailments observed

Brown crisp edges on the leavesDry air or compost that dried right out. Water more evenly and raise the humidity. A fern that has gone crisp can be cut to the base and will usually resprout if the roots are alive.
Yellow leaves at the bottom of the plantToo much light, or hard water building up in the compost. Move it out of the sun and flush the pot through with rainwater every couple of months.
