So I bought a few plants to start my fish tank, and the one that concerns me is the cabomba. One of the stalks was an inch or two shy of the top of the water when I bought it, however, I wasn't expecting it to grow so fast. Now, I have 2 stalks that are bent in all kinds of weird shapes around the tank because it's too tall to fit underwater otherwise. Should I trim them? Or just let them grow? Cut the stalk in half and replant it?
