Anubius Nana and nana petite stay smaller. Bucephalandra, Moss, bolbitis, Java fern, are all good but you can’t run too much light or you’ll get algae. They don’t grow fast enough to uptake excess nutrients or light so algae will get a hold. Use lower powered lighting or add floating plants like salvinia minima or stem plants like hornwort, wisteria, guppy grass...they will block some of the light and will grow fast enough to uptake excess nutrients. Start with a lot of plants so the plants can outcompete algae...don’t start with a few and try to grow them out, algae usually wins
