Süsswassertang

Lomariopsis lineata

plantfreshwater

Often mistaken for a moss, Süsswassertang (German for 'freshwater seaweed') is actually a fern prothallus — the juvenile phase of a fern. It produces small, bright green, tear-drop-shaped cells that cluster into irregular clumps or sheets. Grows slowly and does not need to be attached — it can float freely or be loosely placed on hardscape. Very popular in shrimp tanks and nano setups due to its low-maintenance nature and the intricate hiding spaces it creates for juvenile shrimp.
