Cabomba is a very common and beautiful aquarium plant that is great for beginner aquariums!
Cabomba will root if the shoots are buried in the gravel. The stems will grow up to 50 cm (20 in) and so in an aquarium they will need to be trimmed periodically. They are also easily propagated by simply planting cuttings from the present plants. Cabomba will do great in almost any aquarium environment, including harder water and minimal light. However, the brighter the light the better it will grow.
