What Does Dwarf Hairgrass Look Like In Your Aquarium?

Let us not cap here. You know something just fits in your aquarium when it does not overshadow any other equipment. In simple words, it just fits and makes the aquarium look wholesome.

Dwarf Hairgrass is one of them. Its name itself tells something about its appearance. The plant looks like grass with strands rather than leaves. If you ask me, it gives me coral vibes. Besides, these strands are more like hair as it is really thin.

Similarly, its roots are as thin as its strands and they are white. Thus, these roots are not visible as they stay in the substrate.

It is short if compared to other species of the same type which is why dwarf comes as its first name. Although, you can expect it to reach up to 6 inches making it ideal for carpeting.

Because strands are all densely packed, their true color intensified much more at the bottom of your aquarium. Just wait until your aquarium lights hit these plants! You will be amazed.

How To Care For The Dwarf Hairgrass?

Dwarf Hairgrass can be extremely eye-catching for your tank if you are able to maintain it properly. Here are some things that you can do to care for the Dwarf Hairgrass.

Tank Setup For Dwarf Hairgrass

Dwarf Hairgrass is found almost all over the world. It lives in similar conditions where it’s found. So, it can work in various temperature and water parameters.

Lighting

For lighting, you can use normal aquarium lights. Shallow tropical freshwater plants like these need plenty of access to light.

Recreating its natural habitat is how you can keep it happy and make it grow fast. Besides, doing that is pretty easy since Dwarf Hairgrass is a hardy plant.

To make it grow into a carpet, make sure you do not block its light either by plants or any other equipment in the tank. Otherwise, you will only have scraggly hair.

I suggest you use lights that are customizable so that you can manage the tank and guide it through the algae issues.

For mid-range affordable planted aquarium lights, NICREW ClassicLED Plus Planted Aquarium Light, Full Spectrum LED Fish Tank Light for Freshwater Plants (18 to 24 Inch, 15 Watts) is the best.

Similarly, durable aquarium lights for plants would be Plant Spectrum Fluval Bluetooth Freshwater Light LED (36 inches to 48 inches).

Size Of The Tank

The size of the tank is important to any fish or plant you decide to use. There is no math or rule to keep Dwarf Hairgrass in the tank. You can keep it in small as well as large tanks since it is a small plant.

Substrate

Dwarf Hairgrass does very well with any kind of substrate but you have to make sure you use only 1.5 inches of it.

Besides, make sure you use a substrate that is easy to push through. Sands would be a great substrate for this plant! They also breakthrough gravel but it will take time and is harder.

Dwarf Hairgrass needs CO2 to send out oxygen in your tank. I have the following suggestions for you.

Carib Sea SuperNaturals Peace River (20LB) would be a good substrate if you are looking for one. For Co2 booster, you can use API Co2 Booster Freshwater Aquarium Plant Treatment 16 oz Bottle which is quite cheap as well as effective.

Water Parameters For Dwarf Hairgrass

You have to maintain the appropriate water parameters to make the Dwarf Hairgrass grow at the fast-growing pace that you want it to. The temperature of the water should be around 50° F to 85° F (10° C to 20° C). It can survive in cold temperatures which is the reason why it is distributed widely.

Along with it, you should maintain the pH of the water from 6.5 to 7.5 pH. Likewise, the hardness of the water should be under 2 to 10 KH. If you are able to maintain these things, you will be surprised with a gorgeous tank.

You should definitely avoid extremely acidic and alkaline waters!

How To Plant Dwarf Hairgrass In Your Aquarium?

To plant a Dwarf Hairgrass, you need to find a substrate first. Besides, take extra care that the roots should not be damaged by grains.

Then, determine a place in your tank that would be perfect for the plant. You can also form a layer at the bottom of the plant as a carpet. If you decide to do so, a tip from me is to trim the front blades shorter so that you can see the backside clearly too.

Where you want to plant the Dwarf Hairgrass, there should be plenty of light. If you decide to plant it in a shady area, it will not only just not grow but it might also die.

Put in some aquarium soil and then some substrate. Bury the roots of the plant into the substrate fully and enjoy the strands flowing in the water.

I would say that you should break the grass-like plant into a smaller bunch and then plant them. It would make them grow faster.

Maintaining Dwarf Hairgrass

Maintaining Dwarf Hairgrass is not much work. It is hardy and does great with most water parameters. But, you can still do the following things to maintain it in a proper manner.

Trimming The Blades

To maintain the plant, you might need to trim some strands the weekend they get too long. If you like long blades, you do not have to do that too. If not, you might need to cut more often because they grow pretty fast.

Creating Some Hideouts

You can also create hideouts for your fish dwelling in the middle level by keeping the Hairgrass taller than the back. Because you do not want to block your view but give your fish a sense of safety. How caring are you!

Access To Light

To make Dwarf Hairgrass grow as you want it to, you should plant it in places with access to light. In other words, shaded areas are no-go. If the plants lack proper lighting, you will surely face difficulty in making them grow! Thus, you shall choose wisely.

Nutrients and CO2

If you are providing the appropriate light for your plant but it is still not growing, then lack of CO2 or nutrients can be the cause. Just get them from the store. Be sure to check the effects on fish.

Algae Maintenance

A combination of light, water, as well as plants is the perfect place for algae. So, you might face this problem. Either you are providing too much light or too little CO2.

However, the best way to get rid of algae is to add algae eaters in the tank.

What Problems Can Occur With Dwarf Hairgrass?

Even though it is very easy to care for, the common problems that might occur with your Dwarf Hairgrass are-

Algae Growth

As I have already mentioned before while maintaining the plant in the tank, algae growth can trouble you. So you need to check the nutrients that you are providing to the plant in the water. Make sure you do not give them too much light or too many nutrients.

Difficulty To Grow Or Carpet

Dwarf Hairgrass might not carpet or grow at all. People who have tried this and failed will rate the plant pretty low. But, believe me! The plant is more than that.

You have to give it another chance with proper lighting, nutrients, and substrate. Besides, make sure you do not trim their roots as it stops the growth.

Melting

Melting can occur because you require a heater in a tank and this might be harmful to your plant. The plants might start rotting if you pluck up the dying parts. Therefore, you cannot do anything about it. Just let it grow and it shall be fine.

Propagation Of Dwarf Hairgrass

Propagation of Dwarf Hairgrass is not on your hands. You can only do a few things to help it grow. Otherwise, everything else is the plant’s decision itself.

The first thing to know is that the roots cannot be grown by cutting the plant. You have to wait for it to bloom. And then wait some more for the shoot too.

Do not cut the roots if you want a carpet though. Additionally, there is always some light, fertilizers, and Co2 you can give to the plant to let it grow.

You may also try trimming shoots and maintaining the water parameters at mid-range. These are just tiny efforts to make compared to the other aquatic plants. But, you definitely have to make your waiting game strong!

Tank Mates and Compatibility

Let me start by creating boundaries for its tankmates. The first thing you have to check is whether the fish can live in bright lights or not which most fish do not prefer.

The second thing is to check if the fish you want to have in your tank hates water currents. Since the Hairgrass flows a little with the water, the fish may not tolerate such activity in their tank.

Make sure that you have a smaller tank as these plants only grow better in small tanks and have an attractive appearance like so. Here are some tank mates that find Dwarf Hairgrass attractive with something to know about them too.

Plants

Keep the density of other plants and Dwarf Hairgrass at a similar pace. Not only this, but the Dwarf Hairgrass carpet may also take away all the resources you put in your tank. This means the other plants start to die off which you might not want surely.

Let me mention that other plants with long leaves might get nibbled by fish but with Dwarf Hairgrass, you are good to go.

Fish

The aquarium is incomplete without fish. So, whether you choose a fish for the aquarium and then choose a plant suitable for it or vice versa. Supposing you did the latter one, these are the species of fish you might want to check out to keep in your tank with Dwarf Hairgrass with their care sheet:
