Eriocaulon sp. "Mato Grosso"

Eriocaulon sp. 'Mato Grosso' was originally collected in the Brazilian state Mato Grosso and was imported to Japan by Rayon Vert Aqua, a Japanese company. It is still rare on European and American markets, but quite widely spread among hobbyists in Japan, Taiwan, China and Singapore.

This finicky plant has very high requirements and ought to be kept by experienced aquatic plant keepers only. Lots of light (0,75+ watts per litre) and a high concentration of CO2 (30 mg/l) are recommendable. E. sp. 'Mato Grosso' needs an acidic substrate rich in nutrients and especially rich in nitrate and phosphate for healthy growth. A low pH (around 6) and soft water (4 °KH/4 °dGH or below) are also of advantage.

Eriocaulon sp. 'Mato Grosso' is a slow grower and practically never needs trimming. If it is established in the tank and grows well you can take it out every one or two months for propagation. Cut apart where two leaf rosettes are connected, and separate into two plants.

This Eriocaulon is often seen in tanks where Tonina fluviatilis or Syngonanthus species are cultivated, as its requirements are quite similar. Its grasslike form makes it a great focal point in the aquarium. It is recommendable to place this plant in the fore- or middleground of a tank.
