This tank has CO2 and lots of plants, shrimp, snails, and celestial pearl danios as well as otocinclus catfish. Some of the plants are Tiger lilies, ludwigia, monte carlo carpeting the bottom, crypts, and other stuff I can’t remember the name of. I started an aquarium community as well for anyone to join and share their hobby. https://lemux.minnix.dev/c/aquariums
