How many plant species can I put in 2 gallons?
Right now I have 3 Marimo moss balls, java fern, curly java fern, moneywort, anacharis, and lucky bamboo growing out of the top. I would like to add some other species. Other than running out of planting room because there isn't a lot of floor space in a drum bowl, is there any reason not to add more plants as long as they grow? How much swimming space does a betta really need? Water quality is tops because of all these plants.
Remember that the tank your fish lives in is his or her's whole world. Ask yourself this question, and answer it honestly: would you choose to live there?
