Spider plant (sold as an 'aquarium plant')
Included as a warning. Like several other terrestrial species on aquarium shelves, it survives a few weeks under water, then dies and fouls the tank.

This is not an aquatic plant
It is sold in aquarium shops and will not survive submersed. Expect it to decline over weeks to months and to foul the water as it rots.

Trade-name warning
Sold in aquarium shops as an aquatic plant. It is a terrestrial houseplant and rots when kept submersed.
How to plant it
The commonest way to kill an aquarium plant is to install it wrongly. This is the first thing to get right.
Roots buried, crown above the substrate
Nutrition reaches this plant mainly through its roots, so root tabs matter more than liquid dosing in an inert substrate.
Growing conditions
| Input | Requirement | Notes |
|---|---|---|
| Light | Low | Match plants to the light you have rather than raising light to suit the plant — that grows algae. |
| CO₂ | Not required | Not a requirement, though growth is faster with it. |
| Nutrients | low | Use root tabs in inert substrate. |
| Temperature | 18–28 °C | |
| Growth rate | Very slow |
Propagation
Not applicable — the plant should not be grown submersed.
Emersed growth and melting
Survives with roots in water and leaves in air. Fully submersed it declines and rots.
Common problems
- rots when submersed
- fouls water when dying
Work from the observation: melting, yellow leaves, holes in leaves and poor growth.
Fish and invertebrate compatibility
- Resists grazing
- poor
- Resists digging
- poor
Worth knowing
- It can be grown legitimately in a paludarium or with its roots in the water and its crown above the surface, where it also exports nitrate.

Why we say this
What each figure on this page rests on, and how far that is from being independently established.
Every figure on this page has a provenance. Open any claim to see what AquariumHQ holds for it, which sources say what, and what a claim of that kind actually needs. Different claims need different evidence: an accepted scientific name is settled by one authority, while a legal restriction needs a current primary instrument. A single source is often the right answer rather than a thin one. Light and CO2 categories are aquarium conventions rather than measurements, and are labelled as such — AquariumHQ has taken no PAR readings and does not publish figures it has not taken.
