Hello! I have purple cabomba in my 20 gallon but it's getting really big. Although my dwarf gourami seems to like how it's getting big I kinda want to cut them into pieces and put some in other parts of my 20 gallon and let the new trimmings grow big and start a cabomba forest for him, and add some to float with my betta. I'd plant them but the "substrate" I have for my betta is just really big rocks.
