Question 2

Is Aponogeton crispus native to Sri Lanka?

Accepted Answer

Yes, Aponogeton crispus is native to Sri Lanka and is considered endemic or near-endemic to the island. It grows naturally in shallow, slow-moving freshwater bodies such as irrigation tanks, paddy-field margins, and natural ponds across the lowland wet and dry zones.

Question 3

Can I find Aponogeton crispus in the wild in Sri Lanka?

Accepted Answer

The plant can be encountered in freshwater habitats across Sri Lanka's lowlands, particularly around ancient irrigation tank systems and quiet backwaters. Areas associated with the North Central Province's tank civilisation, and southwest coastal wetlands, are among likely locations. Populations in the wild can be localised and should not be disturbed.

Question 4

Why is Aponogeton crispus popular in aquariums?

Accepted Answer

Its long, translucent green leaves with attractively wavy margins make it one of the most ornamental submerged aquatic plants available to aquarists. It is relatively easy to cultivate in warm water with good lighting and a fertile substrate, and it produces delicate white flower spikes above the water surface.

Question 5

How do you care for Aponogeton crispus in a home aquarium?

Accepted Answer

The plant does best in warm water around 22–28 °C with moderate to high light and a nutrient-rich, fine substrate. It benefits from a short rest period of reduced light and lower temperature once or twice a year, mimicking natural seasonal dormancy. During active growth it can expand quickly and may need occasional thinning.

Question 6

Is Aponogeton crispus endangered?

Accepted Answer

Wild populations face pressure from habitat loss due to wetland drainage and agricultural development, as well as collection for the aquarium trade. While it has not been classified at the highest levels of global threat, conservation of Sri Lanka's freshwater habitats is important for sustaining wild populations long term.
