6" Rabbit's Foot Fern
This might be one of my favourite ferns and it's easy to care for. As the plant grows, those rhizomes will stretch across the surface of the soil (don't bury them) and begin to hang down the sides of your pot.
Medium to lower light, any direct light will scorch those dainty leaves. Ferns must stay consistently warm, moist, and humid. They really hate change, so be sure to avoid any drafts or any conditions where the humidity is going to fluctuate frequently.
