The Dwarf Sagittaria is a freshwater plant that provides multiple benefits to fish and other aquatic creatures that share the same environment.

In this article, you’ll be introduced to the origins of the Dwarf Sagittaria, its uses in an aquarium, as well as how to grow and propagate this amazing plant in your own tank setup.

Getting To Know the Dwarf Sagittaria

The name Dwarf Sagittaria means “small and arrow-shaped”. The Latin word “sagita” (arrow) is the root of the term “Sagittaria”, which is both used as a descriptor and the genus of the plant in question.

The Dwarf Sagittaria originated from the marshes and river basins of South America and some of the southeast regions in the USA. Today, the Dwarf Sagittaria can be found in other areas of the world. Indonesia and the United Kingdom officially classify it as an invasive species.

This tough plant has several names. Scientists will undoubtedly call it by its scientific name, Sagittaria subulata. On the other hand, hobbyists might refer to this plant as Awl-leaf Arrowhead, Dwarf Sagittaria subulata, or just “Sag”. Below is a useful table of quick facts that you can check out to learn even more about the Dwarf Sagittaria.

Scientific Name Sagittaria subulata
Class Magnoliopsida
Order Alismatales
Family Alismataceae
Dimensions 4 to 6 inches in height
Color Bright or Lime Green
Distinctive Physical Features Slender leaves with tapered ends, white roots, occasional white flowers
Aquarium Position All areas or layers of the aquarium
Care Difficulty Easy; recommended for beginners

There are more than 40 verified varieties of Sagittaria plants in the world today. This can make it confusing for new hobbyists to distinguish the Dwarf Sagittaria from other varieties of the same genus. For example, some aquarists think that Dwarf Sagittaria and the Narrowleaf Sagittaria are the same plant; they are, in fact, as different as night and day.

The Dwarf Sagittaria is classified as a small to medium-sized plant with lime green leaves, while the Narrowleaf Sagittaria has darker and thinner leaves, and can grow up to 12 inches in height!

This is why it is important to do your research and check with your local aquatic plant experts when you see a plant you want to purchase online or at a physical store. Veteran fish keepers will know what to look out for. Following the recommendations of experts, you can avoid bringing home the wrong variety of Sagittaria.

Planting and Propagation Methods

Now that you have a more solid understanding of the Dwarf Sagittaria, you can begin thinking about how you should position, plant, and propagate this aquatic flora in your aquarium. Planning for these aspects of including Dwarf Sagittaria in your aquascape can save you a lot of stress and trouble later on.

– Designing a Dwarf Sagittaria-Friendly Tank

Before anything else, you need to ensure that your aquarium meets the minimum water and environment parameters necessary for the growth of Dwarf Sagittaria. You can use the reference table below as a handy checklist when you prepare your fish tank for your new Dwarf Sagittaria.

Temperature 72 to 82 °F; 22 to 28 °C
Light Level Low to Medium Brightness
pH Level 6.0 – 7.5
Water Hardness 2 to 15 dGH
Substrate Nutrient-rich aquarium soil, but may also be grown as a floating plant
Fertilizer/Chemical Additives Substrate fertilizers or liquid water fertilizers
Tank Size 10 to 20 gallons

– The Two Methods of Planting

There are two accepted ways of planting or establishing Dwarf Sagittaria in a freshwater aquarium: substrate planting and free-floating.

  • Substrate Planting

This method is widely used by hobbyists, especially beginner fish keepers who have never cared for Dwarf Sagittaria before. This method is quite straightforward: All you need to do is clear an area for your Dwarf Sagittaria to grow, and then dig a hole about one to two inches deep in the substrate. Place your Dwarf Sagittaria’s roots in that hole and bury it with a light layer of nutrient-rich or fertilized aquarium soil.

Planting Dwarf Sagittaria in aquarium soil will encourage it to spread runners throughout your tank substrate. Given time, these runners will grow into individual plants, effectively creating what is known as a Dwarf Sagittaria carpet.

  • Free-Floating

This method is less commonly used among aquarists but is still a great way to establish a Dwarf Sagittaria in your fish tank. If you want to use this method, all you have to do is leave your Dwarf Sagittaria stems floating on the water surface. The plants will likely sink a little, and it will take some time before they orient themselves as a proper floating plant.

If you use this second method, know that your Dwarf Sagittaria won’t reach its full height of four to six inches. Instead, you’ll see that it develops a lot of roots and thinner leaves compared to the usual planted Dwarf Sagittaria.

– Steps for Easy Propagation

Aside from being easy to care for, Dwarf Sagittaria is also known for being easy to propagate or multiply. In the previous section, you learned that planted Dwarf Sagittaria will eventually spread throughout its tank substrate if it can feed on enough nutrients in the soil.

This means that you can leave your Dwarf Sagittaria alone, and it will inevitably multiply in your aquarium if you do not trim it or actively remove its newer shoots. However, if you want to intentionally breed or propagate this plant, there are a few steps you can take to ensure ease and success.

1. Focus On Nourishing a Few “Mother Plants”

If you have a large tank that houses more than one Dwarf Sagittaria, you might be tempted to propagate all of them. While this is certainly doable, it is not the most effective way to propagate your plants. Instead of trying to multiply all the Dwarf Sagittaria in your aquarium, give most of your attention to robust “mother plants” that have proved to be able to produce healthy and strong leaves.

This will not only help you grow your Dwarf Sagittaria population faster, but it will also ensure that the next generations of the plant are of high quality and in good health.

2. Use Dwarf Sagittaria Cuttings Efficiently

Once your mother plants are ready for trimming, be sure that you have already invested in good-quality planting tools. Using dull scissors or blades, for example, can ruin Dwarf Sagittaria leaves and cause them to die instead of multiply faster.

Cut or pinch off any runners you want to propagate using the proper tools. Double-check that your chosen runners have already developed a root system of their own before you cut them off from the mother stem.

Then, identify areas in your tank that have not yet been covered with Dwarf Sagittaria. Relocating your cuttings to those clear areas can help you cover more of your tank substrate faster. This will also ensure that your new Dwarf Sagittaria has ample space to grow and spread later on.

3. Trim Regularly for a Lush Carpet Effect

This might sound counterintuitive, but trimming your Dwarf Sagittaria regularly will help you achieve a level and lush carpet effect.

Decide on the maximum height and space that you want your Sagittaria plants to occupy. Then, whenever you notice any of your plants exceeding those dimensions, trim them as needed. Your Dwarf Sagittaria will eventually adapt to the regular trimming sessions and adjust to the amount of space it is allowed to occupy.

4. Grow the Young Shoots in a Separate Container

This particular tip is for aquarists who intend to use Dwarf Sagittaria plants as a key component of their aquascapes. Instead of just allowing your Dwarf Sagittaria to spread naturally, you can opt to propagate the shoots from the mother plant in a separate container or fish tank. This will definitely require more resources on your end, but the advantages of using a dedicated propagation tank are worth it.

By keeping all of your Dwarf Sagittaria shoots in an isolated container, you will be able to provide them with an ideal environment for their growth. This increases the chance of your plants reaching your desired height, width, and length without being disturbed by fish or having to compete for nutrients with other flora.

In addition, separating your Dwarf Sagittaria shoots will make it easier for you to select only the healthiest plants to use in your aquascapes. You can also use the separate propagation tank as an environment in which to test the best water parameters and fertilizers for your Dwarf Sagittaria population.

Dwarf Sagittaria Care

Aside from planting and propagating your Sagittaria aquarium plant, there are other things you need to know to ensure that it grows properly. In this section, our experts will provide you with reliable care tips to help you create the perfect habitat for your Dwarf Sagittaria.

You will learn about the best neighbors for your Dwarf Sagittaria, as well as the positive contributions of this plant to the aquarium. You will also read about the common problems that aquarists may encounter when caring for this humble plant.

– Best Aquatic Buddies for Your Dwarf Sagittaria

Some aquatic creatures pair perfectly with the Dwarf Sagittaria. On the other hand, there are also fish that are quite incompatible with this hardy plant.

1. Tetras

Most Tetra fish are peaceful in nature and do not actively feed on plants like the Dwarf Sagittaria. Tetras make for colorful tank mates and will certainly enjoy the shelter and shade from the Dwarf Sagittaria leaves.

2. Shrimp

There are also different kinds of shrimp you can introduce as tank mates for your Dwarf Sagittaria. Some of the types of shrimp that would make great neighbors for Sagittaria plants include the Amano Shrimp, Bamboo Shrimp, and the Red Cherry Shrimp. These aquatic creatures will gladly use the Dwarf Sagittaria’s leaves as shelter whenever they are threatened or as a feeding ground.

3. Catfish

Catfish are also a good choice to house in the same aquarium as your Dwarf Sagittaria. These fish are mostly bottom-feeders, and they are not known for actively destroying aquatic flora. Some of the best species of Catfish to include in a Dwarf Sagittaria tank are Corydoras Catfish and the Pygmy Cory Catfish.

4. Bettas

Bettas or Fighting Fish are another good choice of aquatic creatures to pair off with Dwarf Sagittaria plants. While these fish are notorious for being aggressive towards others of the same species, they are not destructive towards the aquarium’s flora. Bettas will likely take shelter under the plant and will provide pops of color against the Dwarf Sagittaria’s lime green leaves.

– Bring On the Benefits

Aside from its pleasing appearance, the Dwarf Sagittaria has a lot to offer to its immediate environment.

  • Substrate Stability

The Dwarf Sagittaria develops a strong root system that spreads throughout your aquarium’s substrate. This effectively prevents the formation of anaerobic pockets and the buildup of toxic gases in the soil. This makes your soil safer for your tank’s fish and other aquatic creatures.

  • Clean and Oxygenated Water

Like other live plants, the Dwarf Sagittaria plays its part in keeping your tank water clean and oxygenated. Though it is not a water column feeder, it still aids in the filtration of toxic substances and the oxygenation of your aquarium.

  • Spaces for Foraging and Breeding

The Dwarf Sagittaria offers areas for your fish and other aquarium inhabitants to forage, feed, and breed. Your fish will use the soft leaves of the Dwarf Sagittaria as a place to rest, or as a platform on which they can safely snatch at food particles and debris floating in the water.

If you are designing a breeding tank, then your Dwarf Sagittaria will provide the perfect environment in which to raise delicate fish fry.

Common Plant Problems

The Dwarf Sagittaria is one of the most failsafe aquatic plants known in the hobby. However, it is not completely immune to health problems. Here are a few of the most common plant issues that you might encounter when caring for your Dwarf Sagittaria, together with useful tips on how to treat them.

  • Leaf Melting

Novice aquarists are often alarmed when they observe that their Dwarf Sagittaria’s leaves are melting or decaying at an abnormally fast rate. The problem of leaf melting is actually quite common among aquarium plants. It is the result of the plant being shocked by new water parameters or environmental factors.

If this happens to your Dwarf Sagittaria, do not panic. Simply remove the decaying leaves and supplement your plant with liquid fertilizers. This should help your Dwarf Sagittaria adjust to its new surroundings and overcome leaf melting without further action.

  • Yellow Leaves

Dwarf Sagittaria plants that have yellow leaves are most probably suffering from a lack of iron. This is another common problem with an easy solution. Simply supplement your plant’s environment or substrate with fertilizers that focus on releasing iron. You should see improvement in the color of your Dwarf Sagittaria’s leaves after a few weeks of continuous treatment.

  • Pests and Parasites

Dwarf Sagittaria plants are not immune to the pests and parasites that could thrive either in freshwater or brackish tanks. This is why it is important to have a separate container that you can use to quarantine pest-ridden plants and nurse them back to health without passing on their bugs to the other tank inhabitants.

An effective protocol to prevent pests and parasites from destroying your Dwarf Sagittaria is to simply quarantine any new plant or fish and observe them for illnesses or bugs.

You can also use a bleaching solution (25 parts water to 1 part bleach) to cleanse the surface of your new Dwarf Sagittaria before introducing it into its home tank. Rinse the solution off and perform a thorough physical inspection of the plant before actually submerging it in water.
