Experience rapid growth with Heteranthera Zosterifolia, the Star Grass. 

Heteranthera Zosterifolia, known by the intriguing moniker "Star Grass," embarks on a fascinating journey through the aquatic ecosystems of the Americas. This captivating plant is native to the diverse regions of North, Central, and South America, where it thrives in aquatic habitats like ponds, slow-moving streams, and marshes. Its remarkable adaptability to varying conditions allows it to flourish across a range of environments, from tropical rainforests to temperate zones.

In its native habitats, Heteranthera Zosterifolia is part of an intricate aquatic ecosystem, often found submerged among other aquatic plants and aquatic life. Its fine, grass-like leaves serve as shelter and forage for aquatic creatures, contributing to the delicate balance of these ecosystems. The plant's unique ability to grow both submerged and emerged further highlights its evolutionary versatility, showcasing its potential to thrive in dynamic aquatic environments.

The journey of Heteranthera Zosterifolia extends beyond its native origins, as it has found a new home in aquascaping enthusiasts' tanks worldwide. Through meticulous propagation methods like tissue culture, aquarists can enjoy healthy and vibrant specimens of this plant without disturbing natural ecosystems. As Heteranthera Zosterifolia graces aquascapes, it pays homage to its roots while captivating onlookers with its graceful growth and ethereal appearance. Its journey from diverse American waters to global aquascaping showcases the interconnectedness of botanical life, uniting nature lovers and aquatic enthusiasts in their appreciation for the beauty that thrives both beneath the water's surface and within the creative confines of an aquarium.

 To cultivate thriving Heteranthera Zosterifolia, prioritize optimal lighting (2-4 watts per gallon) and nutrient-rich substrate, fostering vibrant growth. CO2 injection proves beneficial, contributing to robust health. Maintain a temperature range of 72°F - 82°F, a pH of 6.0 - 7.5, and embrace soft to moderately hard water conditions for optimal growth.

Regular water changes sustain nutrient balance while periodic pruning prevents dense growth, allowing for circulation and light penetration. Trimmed portions can even be replanted for propagation. Elevate your aquascape by situating Heteranthera Zosterifolia in the background or midground, complemented by contrasting plants to create an enchanting underwater tableau. With consistent care, this graceful plant will flourish, infusing your aquarium with elegance and vibrant allure.

Like most plants, Heteranthera Zosterifolia will benefit from supplementation such as Seachem Flourish, Flourish Excel, Flourish Nitrogen, Flourish Iron, and other plant supplements.  


This listing is for the tissue culture form of Heteranthera Zosterifolia. Tissue cultures are superior to traditional forms of aquarium plants in many ways. They are produced in a completely sterile environment which eliminates the possibility of them carrying pest snails or algae spores. They have a shelf life (before introduction to the aquarium) of several months if properly maintained and they are housed in a nutrient gel until introduced to the aquarium. To introduce a tissue culture plant to the aquarium, simply rinse off as much nutrient gel as possible, then plant as usual. The nutrient gel will not harm your aquarium.

        This colorful tetra is a true aquarium hobby classic!

        These little tetras are one of the more beautifully colored fish available in the freshwater aquarium hobby!  They have a silver body and feature a shimmering red/pink stripe throughout the middle of their body.  Their eye-catching coloration has made them one of the most popular fish for freshwater aquariums today.  They are great for beginners and experts alike, and they thrive in any well-established aquarium that meets their recommended water parameters.  These fish stay small, growing no larger than one to two inches, which makes them an excellent choice for small-sized tanks!

        Glowlight Tetras are very peaceful and make great additions to community aquariums.  However, they should only be kept in tanks with other non-aggressive fish that are similar in size.  They are a schooling fish, and their schools create a magnificent display of colors in motion that has to be seen to be believed!  These fish do best in densely planted aquariums with plenty of hiding places.  This can be achieved with rocks and caves, driftwood, and live plants (good ones include mosses or tall plants that will reach the middle level of the aquarium, such as green cabomba, moneywort, java ferns, etc.).  Since they are a schooling fish, they can really only thrive in groups, which is why we sell them in groups of 6 and 12.

        Glowlight Tetras spend most of their time within the middle and top levels of the aquarium.  These fish are not recommended for new tanks, as they may have problems in tanks that are not well-cycled.  It is important to acclimate Glowlight Tetras to a new tank slowly, because they can be sensitive to changes in water parameters.  They are known to be difficult to breed in captivity; the water conditions must be perfect for them to spawn.  Interestingly, the bright colors on these fish tend to become dimmer at night.  This is normal and does not indicate sickness or weakness in the tetras.

        Iridescent red stripe that add bright bursts of color to any aquarium set-up

        Its small size makes it an ideal candidate for the nano aquarium

        Here at Aquatic Arts, we consider the welfare of the live animals we are shipping to be of the foremost importance. This process is much more involved than simply creating a shipping label and affixing it to a box. Depending on the order, it takes from 4 to 7 people to complete this process properly. We check the weather conditions here where they fly out of the Indianapolis UPS facility and the destination for each shipment. We start early each morning and go through a multi-step process to have the day's shipments prepared in time for the UPS pickup. The volume of orders in our system also affects the processing time. Therefore our stated handling time is 1-9 business days. 

        Shipping Rate

        Q: How often should I feed Glowlight Tetras?

        Q: What should I do if my Glowlight Tetras are not schooling?
        A: Ensure you have at least 6-12 Glowlight Tetras, as they are schooling fish and feel more secure in larger groups. Also, check if there are any stressors in the tank such as aggressive tank mates or poor water quality.

        Q: What signs of illness should I watch for in Glowlight Tetras?
        A: Watch for changes in color, fin rot, spots, or unusual swimming behavior. Common illnesses include ich, fin rot, and swim bladder issues. Quarantine affected fish and treat the tank if necessary.

        Q: What lighting conditions do Glowlight Tetras prefer?
        A: Glowlight Tetras thrive in subdued lighting conditions, which mimic their natural habitat. Moderate lighting with plenty of plants for shade creates an ideal environment for them.
