Ranunculus trichophyllus, the threadleaf crowfoot, or thread-leaved water-crowfoot, is a plant species in the genus Ranunculus, native to Europe, Asia and North America. It is a herbaceous annual or perennial plant generally found in slow flowing streams, ponds, or lakes. The daisy-like flowers are white with a yellow centre, with five petals. It is similar in form to Ranunculus fluitans (river water-crowfoot), apart from flower petal number, thread-leaved has on 5 petals and shorter leaves, as thread-leaved prefers slower flowing waters. It also has rounded seed heads which become fruits covered with bristles. The segmented leaves and the plants ability to photosynthesis underwater have been studied.
Soft, acidic water, subdued light, sand, roots and fallen leaves: how to set up a biotope aquarium from the Amazon and the rivers around it.
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.
