Lemna trisulca L. (syn. Staurogeton trisulcus (L.) Schur; star duckweed; ivy-leaved duckweed) is a species of aquatic plants in the arum family Araceae. It has a subcosmopolitan distribution. Unlike other duckweeds, it has submerged rather than floating fronds (up to 12–14 m (39–46 ft) below the surface), except when flowering or fruiting. Also unlike other duckweeds, a large number of fronds remain attached to each other at a time.
Hard, alkaline water, sand and rock: an aquarium from the rivers and lakes of Mexico and Central America, with cichlids and livebearers.
Two completely different aquariums: forest rivers with soft, brown water, roots and leaves, and Rift Valley lake cichlids in hard, alkaline water with big rock piles.
Two aquariums from Southeast Asia: calm forest streams and peat swamps with soft, brown water, and fast mountain streams with cool, oxygen-rich water.
The home of rainbowfish: water, substrate, plants and light for rainbowfish, blue-eyes and peacock gudgeons, with a long aquarium and open water in the middle.
