What is Elatine hydropiper?

These aquatic plants, also known as eight-stamen waterwort. It is a small plant from the Elatinaceae family.

The “Elatine” genus is a group of aquatic plants, with only 25 species included in the Elatine hydropiper.

Hailing from Europe Northern China and East Asia, this plant was first introduced as an aquarium plant in 2010.

Fast-growing carpeting plants were a problem for many aquarists until 2010, as they required frequent trimming. Therefore, soon after introducing this plant, it hit the market like fire.

It is best to place These aquarium plants in the foreground, as it has tiny leaves with a creeping growth.

Otherwise, this plant will rapidly turn yellow or wither. However, you can easily inject CO2 using a pressurized CO2 setup or a DIY kit.

There are plenty of tutorials on setting up a CO2 injection system on Youtube.

How do you propagate Elatine hydropiper?

Propagating this plant is pretty straightforward. You can propagate Elatin Hydropipers from Runners, Cuttings, Splitting, and cutting off daughter plants.

Either way, this plant will start to grow again if it receives proper care.

However, before you get to propagate, you will first have to grow the plant in your aquarium.

For that, you will have to buy a tissue culture cup from the aquarium shop. The plant in this cup is not the regular type plant you will see in the aquarium. 

The tissue culture plant (cup) is propagated in a laboratory in vitro-style to ensure that the plant is pest-free for the customer.

After you’ve collected the tissue culture plant, remove them from the cup as soon as possible. Then wash out the liquid or gel they’re planted in.

After removing the wax, massage the roots lightly. This will ensure that all of the gel has disappeared from the roots.

You may now distribute the plant throughout your aquarium as directed if you allow the roots to be free.

After several days, the plant will start to grow, multiplying. Once the plant establishes in the tank, you can start propagating this plant.

Can Elatine hydropiper grow out of water?

Elatine hydropiper is an exclusive foreground plant that needs a substrate to grow. Therefore, this plant can not grow out of water.

Elatine hydropiper Tankmates 

Elatine Hydropiper likes bright lighting, so it’s best suited for nano tanks with intense lightings. Therefore, the tankmates should be able to live in such conditions.

Fish

Since this plant is widely sold as tissue cups to ensure no pests in the plant, Elatine hydropiper carries no risk to the fish in your aquarium.

As this is a foreground carpet plant, most fish do not bother with this plant. However, some fish do.

Elatine Hydropiper can be combined with almost any other fish species because Elatinaceae does not contain any allelochemicals.

Elatinaceae is not toxic if the fish consume it, so that you can combine Elatine hydropiper with any species of fish.

However, the fish should be able to tolerate high light conditions as this plant requires it.

Other Plants

You can combine this plant with any midground or background plant, but be sure to set up your tank to provide most of the light to this plant.

The midground and background plants should not cover up the lighting to this plant.

Snails and shrimp

Elatine Hydropiper leaves are soft by themselves, but Elatine Hydropipers‘ roots are pretty tough. So, snails and shrimp can easily damage Elatin Hydroppier’s leaves by chewing on them.

However, you should not worry about Elatin Hydroppier too much as this plant is more resilient than other carpet plants like Micranthemum Monte Carlo or Glossostigma Elatinoides.

Elatine Hydroppier is relatively easy to grow and can handle a lot of abuse from snails and shrimp, but you should still keep it away from your invertebrates as much as possible.

Diseases and Common Problems, treatment 

Elatine hydropiper is a resilient plant with very few diseases and common problems.

Elatine hydropiper can handle a lot of abuse from snails, shrimp, and other species in your aquarium as long as you give them enough light and nutrients to grow properly.

However, the plant’s leaves will burn if the lighting is too intense or not intense enough for this plant. Elatine Hydropipers’ leaves will also burn if the CO₂ concentration is too low.

Elatine Hydropiper can not tolerate less than 40 ppm carbon dioxide, so you should be careful when adding Elatine hydropiper to an aquarium with lowered CO₂ levels.

The poor water circulation will also cause the leaves to burn.

The symptoms and signs of burning leaves of this plant are yellowing of the leaves and developing small round holes in the leaves.

Treatment- Look for the underlying cause for burning leaves. If you don’t provide enough CO2, start providing CO2.

Install an air stone, water filter, or water pump if the water in your tank doesn’t move. Check for the lighting and change accordingly.

How to attach Elatine hydropiper

You can only plant this plant on a substrate because it needs a substrate to establish its root system. Therefore, you can not attach this plant to driftwood, rocks, plastic, or fabric. 

Final thoughts
