Dwarf hair grass (Eleocharis acicularis) is a popular aquarium foreground plant often used in aquascapes to create a grass-like carpet look. It's decorative, not too difficult to grow and shrimp love it. You can keep your dwarf hair grass lawn short by trimming regularly, or let it grow tall to provide your shrimp with a great place to hide and forage. You can even grow it emersed!
Keep reading for everything you need to know about Eleocharis acicularis care and growing this plant in your home aquarium.
Like many other carpeting plants, dwarf hair grass does have some requirements. If these aren't met, the plant will quickly start losing its shape or fall prey to algae, which can quickly cover and suffocate it. This leads to brown patches and very slow growth.
To keep your Eleocharis acicularis looking its best, provide medium to high light. In low-light conditions it will start to etiolate and grow too tall to work as a carpeting plant. Extra nutrients in the form of root tabs, Co2 and liquid plant food are definitely appreciated. Be sure to keep an eye out for any deficiencies by regularly testing your water. Keep in mind that very fine sand or very coarse gravel aren't ideal for this plant: coarse sand works best. It allows the roots to take hold and spread quickly.
Regular trimming is a must with any carpet plant and this is no different for Eleocharis acicularis. Cutting the tops of the leaves helps it maintain its grassy look and actually stimulates new growth. If you want to expand your carpet you can always separate a few clumps and replant them in different places. After all, this plant will spread by itself, but it can take a while before it covers the entire bottom!
Aquascaping - Eleocharis acicularis looks great when combined with taller (stem) plants. Many aquarists also use it in combination with one or more other foreground plants for a little extra variety in textures.
A relatively fine gravel should be alright, but the best medium for dwarf hairgrass is coarse sand.
When buying dwarf hair grass, keep in mind that, like many other aquarium plants, it might not always be labeled correctly. For example, Eleocharis parvula is another aquarium plant commonly known as dwarf hair grass and the scientific names are often used interchangeably. Luckily this isn't much of a problem unless you're really set on one particular hair grass type, as care requirements are pretty much the same.
