The Cyprus grass doesn't just look good in the garden pond and in the pot in the room. It is so flexible and water-loving that it can even be placed in the middle of the aquarium. However, this hydroculture requires a certain background knowledge.

Open, bright and warm aquariums
In general, aquariums that meet the following site parameters are suitable for culture:
- open minded
- 15 to 30 °C warm
- bright (preferably sunny half day)
- pH between 5.0 and 9.0
- Capacity: 25 liters to unlimited
Cyperus helferi - the perfect Cyprus grass species for the aquarium
In addition to other species, Cyperus helferi is particularly recommended for aquarium culture. This species is native to Thailand and lives underwater. It has long narrow leaves and a small root system. The leaves do not begin to rot on contact with water. This species can grow up to 35 cm high and 25 cm wide.
The optimal location for this Cyprus grass is in the middle ground of the aquarium - ideally as a solitary plant. The temperatures should be between 20 and 30 °C. Usually this species can cope for a long time without care - it grows extremely slowly.
Put the Cyprus grass in the aquarium
If you have chosen a Cyprus grass other than Cyperus helferi for aquarium culture, you should consider this:
- Spread pebbles on the bottom of the aquarium
- there the roots hold fast
- Leaves of the plant should not touch the water
- or water level not higher than the leaf tufts
If necessary, remove disturbing roots, fertilize and cut
Fish like to swim through the threadlike roots of the Cyprus grass. Sometimes it overgrows so much that it creates a whole 'forest'. If you are bothered by this, you can cut the roots, divide the plant or shorten the height. A conventional aquatic plant fertilizer is sufficient. If you want to get offshoots, you only need to cut off the tufts of leaves and put them upside down in water.
tips
Do not be surprised if the Cyprus grass hardly noticeably grows in the aquarium in winter! The incidence of light is usually too low in winter, so that the Cyprus grass enters a dormant phase.
