I am planning on adding very slowly. My tank is actually 29g running 2 filters- a Topfin Silentstream 30 and and ACO Medium Sponge Filter, plus the plants I’ve mentioned. I may wait awhile until some of the fast growing plants grow and spread. As is now, I water change every 3-4 weeks when nitrates reach 50ppm. I definitely will be adding the Pandas to increase their group. The Chili Rasbora were just something I’ve always wanted to keep a larger school of, so they may or may not go in- instead, I may try to increase the Cardinal school.
