Aquarium Plants in Sri Lanka – Aponogeton rigidifolius

Aquatic plants are used to give the aquarium a natural appearance, oxygenate the water, and provide habitat for fish  and for invertebrates.

෴  Aponogeton rigidifolius  ෴

Aponogeton rigidifolius is native to Sri Lanka. In the wild it grows in deep water at temperatures of 68 to 77F  in sandy soil with the water pH at 7.2.

Plant Description

The creeping rhizome is cylindrical and about 0 .5 inch  thick. The leaves stay submerse, are firm  about 8 to 23 inches long ) and 1 to 1.6 inches wide . The margins of the leaves are flat to slightly undulate with a distinct midrib. In color they are a dark green to reddish color. The inflorescence has a single spike with white flowers and small fruits.


This species is unique amongst the Aponogetons in having an elongated rhizome rather than a tuber which creeps along the surface and from which new leaves sprout. This rhizome can be divided.  It needs only a moderate light, tropical temperatures, and will tolerate harder water than most other Aponogetons. It is not commonly available but a good plant for the middle to background of an aquarium.

Farm Frenzy 1,2,3

The goal in a Farm Frenzy game is to raise animals, process the goods they produce and sell the products for cash. To raise animals, the player must regularly water the grass they eat. A well with a limited capacity supplies the water and costs money to refill. Once the player buys an animal, the animal starts eating grass and dropping goods for the player to pick up. For example, chickens lay eggs, sheep produce wool and cows produce milk. The goods the player picks up are stored in a warehouse with limited capacity. From there, the player may either sell the goods by having a truck transport them to town or turn them into more valuable goods using a specific processing facility.
