Heteranthera zosterifolia In-Vitro

Lilaeopsis brasiliensis / Brazilian grass plant max. growth height - 8 cm Country of origin Argentina, Paraguay, south-east Brazil Suitability Community aquariumNano Cubeaquascaping Type Stolons Family Apiaceae Genus Lilaeopsis Propagation Stolons Growth rate medium pH 6 - 8 Water hardness 0 - 20 °dh Notes   Lilaeopsis brasiliensis is a decorative foreground plant. In its natural habitat it colonises the banks of rivers and swamps up to an altitude of over 1,000 m. Its grass-like character is similar to that of Helanthium tenellum, which is why it is sometimes referred to as "false tenellus". It is easy to cultivate in the aquarium, prefers cooler water and grows quite slowly, regardless of whether the water is soft or hard. Strong pruning, as with a lawn, promotes compact growth. It needs plenty of light.

Rotala Rotundifolia 'Green' Rotala Rotundifolia 'Green' (Round-leaved Rotala) is a mid-ground plant. It is characterized by fast growth and moderate light requirements. The color is usually light green.Difficulty of growing: easy Light requirements: medium CO₂ requirements: not necessary Height of mature plant: 50-60 cm Growth: fast Temperature: 20-28°C Placement in aquarium: third level Origin: South Asia, Southeast Asia Cup diameter 6 cm The natural range of the round-leaved Rotalas (Rotala rotundifolia) is South, Southeast and East Asia. It has been spread by humans to Australia, the United States and Brazil, among other places. She is thus already almost a globetrotter.Rotala rotundifolia 'Green' is very similar to Rotala rotundifolia, but its leaves remain bright green even in bright light. This plant is characterized by its fast growth and its tendency to spread profusely, especially when regularly pruned. It tolerates medium light levels, but the higher the light, the more intense the plant's growth and colors. If left to grow freely, it reaches a length of 30-60 cm, cutting off access to light to the lower parts, where it begins to lose its leaves. Under favorable conditions, if left uncontrolled, it can dominate an entire tank, especially if it is a tank with a small capacity. Once it reaches the surface of the water, it begins to float on it. It does not need additional carbon dioxide fertilization unless you want to accelerate its growth even more. It is tolerant of pH and water hardness, although like most plants, it cannot tolerate extremes. It tolerates temperatures between 20 and 28 °C, but thrives better in the upper end of this range. It can grow in both an active and a poor substrate, but in this case it is advisable to fertilize under the roots. In well-lit, CO2-fertilized aquariums, it may require additional fertilization with macronutrients due to its rapid growth. Otherwise, it will lose its color and the leaves will become smaller. Rotala rotundifolia is propagated in the aquarium by cutting off stem pieces and placing them in a selected spot in the substrate. When transplanted to a new tank, it will need some time to acclimate and grow faster.Planting: The plant must be removed from the cup and thoroughly rinsed from the gel under running water. This is best done by placing the plant in a container of lukewarm water. Most of the gel will then fall off by itself. Divide the contents of the cup into 1-2 cm lumps and then place them at a small distance into the substrate.

Sagittaria subulata var. pusilla - Dwarf Arrowhead max. growth height 10 - 40 cm Country of origin USA / South America Suitability Discus aquarium, NanoCube and community aquarium Type Rosette plant Family Alismataceae Genus Sagittaria Propagation Stolons Growth rate medium pH 5 - 8 Water hardness 0 - 15 °dh Notes   The small arrowhead is a popular aquarium plant with very narrow, ribbon-shaped leaves. At first glance, these look very similar to the leaves of Vallisneria. The growth height of Sagittaria subulata var. pusilla is very variable, ranging from a few centimetres to 40 cm. Only with good lighting does the arrowhead stay nice and short for the foreground area. The plant carpet can be kept short by regularly removing runners with longer leaves. This species grows best in medium-hard to hard water and is very tolerant when it comes to water temperature.
