Types of Aquatic Plants:


  • Foreground plants: These low-growing beauties are typically used in the front of the tank, adding depth and visual interest. Popular choices include:

    • Dwarf hairgrass

    • Dwarf sagittaria

    • Small cryptocorynes variants like x willisii, parva

    • Monte carlo

    • Glossostigma elatinoides

    • Alternanthera Reineckii 'Mini'

    • Smaller variations of anubias like barteri var. glabra or nana "kerin" and nan pinto

    • Smaller variations of bucephalandra

    • Blyxa japonica

    • Eriocaulon cinereum

    • Hydrocotyle tripartita

    • Lilaeopsis brasiliensis

    • Marsilea hirsuta

    • Micranthemum callitrichoides 'Cuba'

    • Pogostemon helferi

    • Ranunculus inundatus

    • Staurogyne repens'

  • Midground plants: Placed in the middle section, these plants provide a transition between foreground and background elements. Popular options include:

    • Various sword plants

    • ludwigia species like repens, glandulosa and super reds

    • Rotala species like rotundifolia, macrandra, and wallichii

    • Java Ferns

    • Larger variations of anubias

    • Alternanthera Reineckii Rosanervig

    • Larger cryptocorynes variants like wendtii, undulata, and beckettit "petchii"

    • Echinodorus 'Reni'

    • Echinodorus 'Aquartica'

    • Hygrophila corymbosa 'Compact'

    • Hygrophila pinnatifida

    • Nymphaea lotus

    • Sagittaria subulata

  • Background plants: These tall and majestic plants create a stunning backdrop, adding verticality and hiding equipment. Most of the time we use tall going stem plants, or plants that get really large. We don't want to put them into the front or middle ground as they will block plants behind them. Popular choices include:

    • Amazon sword

    • Water sprite

    • Various Vallisneria species like spiralis tiger and americana gigantea

    • Alternanthera reineckii 'Pink'

    • Aponogeton boivinianus

    • Bacopa caroliniana

    • Hygrophila corymbosa

    • Hygrophila pinnatifida

    • Pogostemon stellatus

Functions of Aquatic Plants:

  • Provide oxygen: During photosynthesis, plants release oxygen, essential for the respiration of fish and other aquatic life.

  • Reduce algae growth: Plants compete with algae for nutrients, helping to control unwanted algae growth in your tank. Happy plants also produce allelochemicals which are a natural defence mechanism against agale, for the plants themselves, but planted tanks as a whole.

  • Offer hiding places: Lush foliage provides shelter and reduces stress for fish, especially shy or territorial species. They also provide areas for spawning and protection for small fry.

  • Improve water quality: Plants absorb excess nutrients from the water column, helping to maintain a healthy balance and reduce the need for frequent water changes.


Essential Care Tips for Beginners:

  • Research plant needs: Different plant species have varying requirements for light, water flow, and nutrients. Choose plants suited to your tank conditions and ensure you can provide their specific needs.

  • Provide adequate lighting: Most plants require moderate to high lighting for optimal growth. We'd suggest that you read over our lighting guide which goes over the essentials for choosing a planted tank light, and we even make a few suggestions for you at the bottom of the article.

  • Fertilize appropriately: Plants love themselves some fertilization. The 1-2 punch is an aquasoil paired with a good fertilizer like Thrive or the ASG Fertilization Kit. We'd suggest that you read over our nutrients guide which covers this approach to keeping your plants happily fed.

  • Maintain proper water parameters: Regularly monitor and maintain water parameters like pH, temperature, and hardness within the ranges suitable for your chosen plants. Most planted tanks can run at a GH and KH of 4. We cover this in our water parameters guide in which you can read here.

  • Consider CO2 supplementation (optional): While carbon is an essential building block for all plants, CO2 injection is not essential for all planted tanks. With that being said, injecting CO2 can significantly enhance the growth and health of many aquatic plant species, especially those requiring high light. However, CO2 injection requires careful monitoring and proper equipment to avoid harming fish and invertebrates. If you are looking to get into CO2 we'd suggest you take a look at our CO2 guide.

  • Trim and propagate regularly: Regular trimming encourages healthy growth and maintains the desired shape of your plants. Propagated trimmings can be used to create a denser and more visually appealing aquascape.



With a little practice, the right care, and a touch of creativity, you can cultivate a thriving underwater garden that not only enhances the beauty of your tank but also contributes to the overall health and well-being of your aquatic residents.


Remember, this is just the beginning of your exploration into the captivating world of aquatic plants. As you gain experience and delve deeper, you'll discover a vast array of unique and stunning species to add to your ever-evolving underwater masterpiece.
