Is there a Lowe's near you? I saw some very small ones in their houseplant section this afternoon but I wasn't in need of one so I didn't pay much attention to the name.
If you are buying on line you may find Ebony spleenwort fern or Dwarf Polypodium tongue fern. I love the Polystichum setiferum. Some actually get very large but you can always trim them back to the size of your little world. Barb in Pa.
(Java Fern) an aquarium fern is not a marginal plant. I think the leaves would dry out. It really needs to be under water. It is one of my favorite aquatic plants. Barb in Pa.
