This genus from family Elatinaceae or Waterwort is originated from Eastern Asia and Europe. Elatine hydropiper is a creeping stem plant where the leaves size around ½-1 cm grow on the creeping stem forming a carpet. They grow in ponds, rivers and marshes in nature and usually used in aquaria as foreground plants. It’s height about 2-5cm and could grow to width around 2-30cm. They grow compact, round and green light leaves. Elatine hydropiper very much resembles Glossostigma elatinoides but have smaller leaves size. Its size made it ideal for nano tanks.
To plant the carpeting plant, finer tweezer is advisable. Plants should be divided into several portion or pieces and planted with similar gaps for a good ground coverage. This plant requires good lighting (0.5-1watt/L) and stable CO2 additive (6-15mg/l) for them to grow beautifully and dense. Although they can tolerate moderate light without addition of CO2, the stated environment is highly recommended for optimal growth. Elatine hydropiper also need good water circulation to avoid the leaves from turning yellow and forming holes which is often mistaken as potassium deficient. The advantage of this plant is that less trimming is required as their growth rate is medium compare to Glossostigma elatinoides.
