Aponogeton longiplumulosus
Also sold as Longiplumulosus
Aponogeton longiplumulosus is a bulb plant for the background, growing to about 50 cm (19.7 in) at a fast pace. It wants 68–82°F (20–28°C), low light and no CO₂, and counts as a medium-difficulty plant to keep alive.

Before it goes in
- Aponogeton longiplumulosus lives under a plain low-light LED — it does not need a planted-tank lamp to survive.
- It grows without CO₂.
- It feeds through its roots, so in plain sand or gravel it needs root tabs; in an aquasoil it does not.
- 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 medium: Goldfish, Electric Yellow Lab and Colombian Ramshorn Snail will eat it.
Can it grow without CO₂?
Yes. Aponogeton longiplumulosus does not need CO₂ at all.
How much light does it need?
Low light is enough — and that is the survival line, not the “it looks better” line.
How big does it get?
About 50 cm (19.7 in) tall when it is mature and untrimmed, growing fast, after roughly 3 weeks to root in.
Will my fish eat it?
Its leaves are medium, so some will: Goldfish, Electric Yellow Lab and Colombian Ramshorn Snail.
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: Hygrophila corymbosa 'Siamensis', Water Sprite, Anubias nana 'Petite' and Cryptocoryne wendtii.
- Animals that share its temperature range and will not eat or uproot it: Betta, Cherry Shrimp, Angelfish and Bristlenose Pleco.
