Okay I have a list of the commonly sold plants in the pet stores in the city (going there this Saturday!) And I am wondering which ones are okay... It's a 20 gallon and someone pointed out I needed taller plants :)
Cabomba plant: I haven't heard of this one, but it looks nice.
Hornwort plant: pretty sure some people on here have them
Wisteria: I know this one is compatible with bettas, I've heard people have them :)
Moneywort plant: never heard of it
kyoto plant: again never heard of it?
Anubius plant: I think someone here has them?
Medium sword plant: That'd be a tall one for them right?
Anarchis plant: don't think I have heard of it
Java fern plant: I know people have this one :)
My 20 gallon has purple gravel, that's smaller than my regular gravel. Any plants that don't need special care would be lovely... like, no special substrates and such :) I want to go in already knowing, and have heard your experiences with certain plants, then go in blindly. That way no "but the employee said" problems!
