10 Emergent Aquarium Plants for Fish Tank | Must Know

Emergent aquarium plants are plants that stand above the water surface for various reasons, such as accessing Carbon Dioxide from the air and getting natural sunlight for optimal growth.

Emergent plants are amphibious species that can live along the edges of streams, lakes, or low flood plains. They can spend a considerable amount of time wholly submerged, especially in the rainy season.

Advantages of Emergent Plants in an Aquarium

Growing emerged plants have some advantages over other aquarium decorations.

  • Aquatic plants act as a food source for your fish that eat plants.
  • They provide a natural wildlife habitat for fish to use as a nest or hide to avoid predators.
  • They help improve water quality by absorbing nutrients such as phosphorous and nitrogen, reducing algae growth.
  • Aquatic plants stabilize the shoreline and waterbody bottom by reducing wave action impacts with their roots.
  • They improve the overall beauty of your aquarium by providing a natural atmosphere.

Below is a list of Emergent Aquarium Plants you can grow in an aquarium.

How To Maintain Emergent Aquarium Plants

You can’t have emergent plants in your aquarium within minutes like faux plants.

You have to prepare your tank with suitable soil or substrate and control CO2 levels, iron, and other supplements in your tank. And you have to do all of them, not harming your fish. Growing emergent aquarium plants have many benefits for your fish.

If you successfully grow these plants in your aquarium, your fish will have a natural food source, a suitable habitat, a place to hide from predators, and healthy oxygen straight from the plants. They can also lower the nitrate level of water which is helpful for your fish. So, how should you plant these species, and how to maintain them?

Soil

Some emergent plants need soil to thrive, and some will go fine with aqua soil (which means substrate like gravel). Some plants grow on any surface. You have to check soil requirements before placing your plant in your tank.

After preparing your tank with suitable soil, set them according to the guidelines. Some plants grow large and will be prominent. You have to place those plants in the middle of your tank.

Light

Most emergent plants need at least some sort of light for at least 8 hours per day. Depending on the light level, some plants show vibrant or dull colors. So, check the light requirement of your chosen plant before setting it up in your tank.

If you use direct sunlight for your tank, be sure to cover up with some shelter, as direct sunlight can kill both fish and plants’ aquatic life.

Nutrients

Basically, emergent plants need CO2 and Nitrate for optimal growth. If your tank can not provide them with current conditions, you’ll have to provide them artificially. You can inject CO2 through a diffuser and put Potassium Nitrate (KNO3) regularly to increase your tank’s Nitrate level.

But you have to do that carefully as too much CO2, and Nitrates are not healthy for your fish. Always stick to the guidelines of an expert. Some plants like Water Primrose and Giant Hygro need iron and other fertilizers to thrive.

You have to provide these supplements if you plan to grow such plants. Many emergent plants are hardy and will go fine with water condition changes. Some are even capable of living in cold weather. You don’t have to worry much about water conditions unless you have specific fish species that need particular water conditions.

How To Anchor Emergent Aquarium Plants

Keeping emergent plants in your aquarium is a fantastic idea. But, how do you anchor them? Many emergent aquarium plants are root feeders, while some are Colum feeders. Root feeders grow a robust root system to obtain nutrients. We usually anchor root feeders into the substrate of the tank.

Some root feeders are happy to establish on rocks and ornaments, while some need substrate like gravel to establish their root system. Colum feeders are floating plants. They absorb nutrients from the water. Some Colum feeders have floating roots, while some don’t.

You can directly put Colum feeders into your aquarium. They will start to flow and begin to adapt to your tank.

But how about root feeders? How do you anchor them?

You have few options.

  1. Put some aquarium pebbles or rocks around the plant’s base
  2. Tie the plant roots to some rocks
  3. Wrap the plant, or its roots around driftwood
  4. Keep the plants in their pots and put the pot into the tank
  5. Wrap the plant with Plant Anchors and put them into the tank
  6. Use a thick base of sand to put the plant or
  7. Use a Nylon Mesh to hold them down

The aim here is to hold the plant roots below the substrate until it grows its root system; after the plant forms its root system, the anchors’ need decreases. Aquarium plants help you to make a little ecosystem inside your aquarium. Your fish will thrive and be happy in your aquarium in the presence of emergent aquarium plants as they receive a natural ecosystem, not a prison.
