Dwarf Hairgrass Overview
Dwarf hairgrass is an aquarium plant distributed almost across the globe. It grows in tropical, temperate, and subtropical places which excludes Africa.
It naturally grows along slow-moving rivers, on the edges, and such rivers’ banks. You can also find them growing in marshes, ponds, and swamps where there is considerable exposure to light.
Dwarf hairgrass has two main species, Eleocharis Parvula and Eleocharis Acicularies.
The E. Parvula is a bit lighter in color, but the color deepens with good lighting. It is found in salt marshes in brackish pools and estuaries. E. Acicularies, on the other hand, grows in freshwaters and is also deep green.
The deep green color of dwarf hairgrass can be maintained by sufficient lighting and good maintenance.
As the name indicates, this plant has a short stature but is very sturdy. The plant is also fast growing which means that you can plant it, and in a short time, it will have filled the whole tank. It is used as a carpet for most aquariums.
Dwarf hairgrass, like most aquarium plants, helps to oxygenate the whole tank, thus giving the animal life in the tank a healthy stay. Moreover, the plant helps to filter out some waste in your tank.
How Much Does Dwarf Hairgrass Cost?
Due to its popularity, dwarf hairgrass is always in demand, and you can find it in any of the aquarium shops near you. It is cheap, and you can buy it for as low as $5–$10 for a clump. You will find that the clumps are sold in pots, and a small of wool is wrapped around the roots.
Just because it is cheap doesn’t mean that you should just take the clump handed out to you. Instead, be sure to choose a healthy plant to grow well and last a long time in your aquarium tank.
If you are growing Dwarf hairgrass using its seeds, you can expect to see it grow in about a week or two. This shows how fast the plant grows. Due to its dwarf characteristic, this plant can never grow tall.
It will also depend on how much light you are exposing it to have a brighter color. The more the light, the brighter this plant becomes. The younger shoots of this plant are mostly darker in color, but with time and the amount of light you expose them to, they become brighter.
Appearance & Varieties
This plant appears to be just like the grass you see in a yard but stringy. It also has a curly look when fully grown, where the full growth rate will be at 6 inches long. If you expose it to enough light, the plant becomes lighter in color, giving your tank an aesthetic look.
The roots of this plant are white and thin, but once you plant them, you will rarely see them since they will stay at the substrate. Compared to other aquarium grasses, dwarf hairgrass is a perfect choice for a carpet for the base of your tank since it does not grow tall.
The thin blades become so dense that they are a good base carpet for your aquarium tank. Apart from this, the dense blades also enrich the color making the carpet look more beautiful. Under aquarium lights, this green color becomes even more beautiful making your aquarium a sight to behold.
As earlier mentioned, these strands do not grow more than 6 inches long, so when they reach a 4–6-inch length, they adopt a curly look. They are then swayed by the current in the tank and gently pulled, which makes the animal life in your tank more excited.
However, the curly ends may take over a brown tinge, so take note of this so that you don’t think that there is something wrong with your plant. This, however, takes place when the plant is fully grown and has become curly.
If you notice that your plant has taken over a faded brown color even though it is not fully grown, there must be a problem with it. Both the E. Parvula and E. Acicularies are similar in appearance, except that the E. Parvula is shorter. It also has a deep green color when compared to the E. Acicularies species variety.
