Cabomba aquatica
Synonyms Yellow cabomba
Cabomba aquatica is a stem plant for the background, growing to about 50 cm (19.7 in) at a fast pace. It wants 68–82°F (20–28°C), medium light and no CO₂, and counts as an easy plant to keep alive.

Before it goes in
- Cabomba aquatica needs medium light. Under a low-light LED it thins out instead of filling in.
- It grows without CO₂.
- In too little light it stretches: long bare stems between leaves instead of a bushy plant.
- At about 50 cm (19.7 in) it belongs behind everything shorter — planted at the front it hides the rest of the scape and shades it.
- Its leaves are soft: Goldfish, Common Pleco and Molly will eat it.
Can it grow without CO₂?
Yes. Cabomba aquatica does not need CO₂ at all.
How much light does it need?
Medium light — and that is the survival line, not the “it looks better” line. Below it, this one stretches instead of spreading.
How big does it get?
About 50 cm (19.7 in) tall when it is mature and untrimmed, growing fast, after roughly 2 weeks to root in.
Will my fish eat it?
Its leaves are soft, so some will: Goldfish, Common Pleco and Molly.
What it goes with
- Plants that run on the same light and CO₂, so they can share a tank without one of them being the odd one out: Water Sprite, Anubias nana 'Petite', Cryptocoryne wendtii and Frogbit.
- Animals that share its temperature range and will not eat or uproot it: Betta, Cherry Shrimp, Angelfish and Bristlenose Pleco.
