Damasonium alisma, commonly known as starfruit, is a species of flowering marsh plant. Its native range includes parts of Great Britain, France, Portugal, Spain, Italy, Greece, Russia, Ukraine, Moldova, and Kazakhstan. Damasonium alisma is native to the British Isles and was at one time commonly found in south and central England. Numbers have declined as a result of the loss of pond habitats. It was not recorded in the wild in 2006 and is classified as endangered within the United Kingdom. Seeds from the (extinct) Headley Heath population were germinated in undisturbed ponds managed by Surrey Wildlife Trust in 2013, and have grown there each year since (at least up to 2018).
Two aquariums from Southeast Asia: calm forest streams and peat swamps with soft, brown water, and fast mountain streams with cool, oxygen-rich water.
A coldwater aquarium with European fish and plants, without a heater. The water follows the seasons, and summer heat is the biggest problem.
