plants that don't need substrate

I've had good luck with Marimo moss balls. They just roll around the bottom and don't need anything special. Plus, they're super low maintenance.

Marimo balls are cool but watch out for fake ones. Some stores sell lookalikes that aren't real moss.

True, gotta be careful with those. Real Marimo should feel soft and fuzzy, not hard or plasticky.

Another tip for Java Fern: don't bury the rhizome. Just tie it to something or it'll rot. Learned that the hard way.

Yeah, same with Anubias. Keep the rhizome above the substrate or it's gonna have a bad time.
