Hemianthus callitrichoides is a great addition to your aquarium. It has a bright green color and low-growth, so it adds interest and dimension to the other plantings you have. Hemianthus grows slowly and ends up looking like a rug or piles of moss. It's best to plant this species in the front of your aquarium because most other plants will be taller. Hemianthus callitrichoides is easy to plant and will grow with little maintenance.
Put 1 inch of fine gravel or quartz aquarium sand on the bottom of the aquarium.
Fill the aquarium with room-temperature water. Hemianthus prefers soft water, but hard water is also OK.
Put the plant in the aquarium, while still in its package. This will give it a chance to get used to the water temperature. Wait a few minutes.
Remove the plant from the packaging.
Push the hemianthus into the gravel or sand in the preferred location. Place ball bearings on top of the plants roots to hold it in place.
Keep the hemianthus' roots in place once you weigh them down. They are fine and delicate and can tear if you try to move the plant. Wait a few weeks for the roots to become established in the aquarium.
Attach a strong aquarium light to the top of the tank. Hemianthus needs six hours or more of light every day.
Make several hemianthus plants by dividing them. Allow the plant to grow for several months, then break up the clumps to form new plants.
