Marsilea hirsuta is a good aquarium plant that is ideal for the foreground in an aquarium setting. It is a short plant with clover-like looks that grows slowly and if planted in groups will form coverage like a carpet in the aquarium. After a transitional period it develops different types of leaves, possibly a low form with single leaves like a large Glossostigma, or alternatively develop two, three or four-lobed leaves varying in height (from 2-10 cm), depending on the growth conditions.
