Ebony Spleenwort: curling leaves, causes and fixes

Check these first

Check if the soil is dry to the touch.
Feel the fronds to see if they are crisp or soft.
Move the plant away from any direct heat sources.

Likely causes

Low humidity
Possible
How to tell: The frond edges will curl inward and feel crisp or dry to the touch. This happens when the air is too dry for the fern's tropical needs.
What to do: Place the fern on a pebble tray filled with water to increase local humidity. You can also group it with other plants to create a more humid microclimate. Avoid placing it near heating vents or drafty windows.
Underwatering
Possible
How to tell: The entire frond may curl and droop as the plant loses turgor pressure. The soil will feel very dry and pull away from the sides of the pot.
What to do: Water the plant thoroughly until water runs out of the drainage holes. Ensure you are watering every 3 to 7 days depending on your home environment. Do not let the soil dry out completely.
