Glossostigma elatinoides from New Zealand is one of the smallest aquarium plants (2-3 cm tall), and thus a good foreground plant. A difficult plant demanding a lot of light. Grows upwards if light is poor. Make sure larger plants do not overshadow it. When planting in the aquarium small clumps should be placed at intervals of a few centimeters to help the plants grow together more quickly. CO2 addition and soft water promote growth significantly.
Hemianthus callitrichoides is one of the smallest aquarium plants in the world, and creeps over the bottom with millimetre-sized round leaves. If planted in small clumps a few centimetres apart, it will spread rapidly and cover the bottom like a carpet. Hemianthus callitrichoides is an attractive foreground plant for small aquariums. Found on Cuba west of Havana.
Lilaeopsis brasiliensis is a short-stemmed plant that can be grown as a carpet in an aquarium. It is found throughout much of Brazil, and it grows both fully submersed and partially submersed on the banks of rivers and streams.It will grow to a maximum size of 3 inches (7.5 cm) in a home aquarium, and will form a dense and impressive carpet if it is provided the right mix of CO2, nutrients and lighting. This can be a somewhat difficult plant to grow, and should only be attempted by aquarists who have some experience with aquatic plants.
Marsilea hirsuta is a carpet-plant from Australia. A fascinating plant, usually delivered with leaves like a four-leaf clover. 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 ,depending on the growth conditions. Whichever form the plant adopts, it forms runners and spreads rapidly round the aquarium.
Micranthemum ‘Monte Carlo’ comes from Argentina. It has compact, round and fresh light green leaves on creeping stalks and creates a fast-growing carpet in the front of the aquarium. The plant can grow in light shadow, but requires good light conditions, as well as CO2 additive, in order to develop optimally and become really compact.
