Benefits of Live Plants in Fish Tank


Research shows that live plants are far more than design for freshwater fish. In reality, research studies discover that the majority of freshwater neighborhood aquarium fish choose live aquarium plants to their plastic counterparts. This is no doubt because live fish tank plants are an essential part of producing a natural or close to natural surroundings for much tropical freshwater fish.

In a well-planted fish tank, fish can find shade from glaring light, privacy from things beyond the tank that surprise them and a natural safety in times of stress. Live plants allow smaller sized, shyer fish to evade bigger or aggressive tank mates or over-eager possible reproducing partners. For shoaling fish, plants provide the group the currents and eddies they naturally seek out in the wild.

Main Benefits of Having Live Plants in Fish Tank

Without a doubt, the most significant benefit that live plants attend to your aquarium is that they produce oxygen (O2) and soak up the carbon dioxide (CO2) and ammonia (NH3) that your fish generate. Adding live plants in your aquarium helps recreate a natural community in mini, and might be one of the most helpful methods to keep your fish healthy.

Plants supply shelter and security for the fish. Because they compete with algae for nutrients, they can assist to lower algae growth. Live plants improve the look and offer a far more natural environment for the fish. By enhancing water quality and reducing stress, live plants are a great method to increase your fishes’ health. Adding live plants, nevertheless, does not lower the need for water changes. When choosing live plants, make sure that you select types that are true aquatic species and that appropriate for your specific water type and fish types.

When breeding many types, live aquarium plants are essential surfaces for the deposit and fertilization of eggs. Live aquarium plants have natural infusoria and other essential algae clinging to them or growing from them that feed the newborn fry of lots of types.

1) Care and Needs of Freshwater Aquarium Plants

Live aquarium plants need three fundamental things to stay healthy and supply essential advantages in the aquarium environment.

  • Enough lighting replicates the favorable properties of the sun. The much deeper the tank, the more powerful the lighting system needed.
  • The proper substrate keeps live plants anchored and offers a fertile area for root growth. Fine gravel, specifically designed terracotta gravel or sand works best for a live plant environment. Never use dirt or loam soil of any kind in a freshwater neighborhood aquarium environment. “Dirt” or “pond mud” can reproduce dangerous germs unless sterilized, and if purified, the loam is of little or no use to plants.
  • To supply adequate food for the live fish tank plants, a popular freshwater aquarium will have some nutrients in the substrate. A new aquarium needs to be supplemented with live aquarium plant food which is extensively available. Even well-established fish tanks need to be supplemented with extra nutrients for maximum benefit to the community fish tank as a whole.

2) Ground Cover Plants

Vallisneria and other ground cover plants send “runners” which become new rooted different plants. These new plants can be broken off as they grew and moved to another location in the tank or another fish tank totally as a new feasible plant.

These true aquatic plants are great for ground cover and ought to be placed in the back of the aquarium since many species grow high. It must be noted that these “real aquatic” plants cannot tolerate a dry condition, so do not eliminate them from the fish tank and enable them to dry out as this will seriously harm or eliminate them. Even moving from fish tank to fish tank or from shop to home fish tank need to be carried out in a container of water. Air damage can take place rapidly and makes plants unsightly for weeks.

3) Node Propagators

Myriophyllum, Ludwigia, and Acorus, in addition to lots of other plants frequently discovered in fish tank stores, are node propagators. Their long stringy branches quickly break off and drift on the surface of the aquarium. These loose branches can be collected in a small bunch, anchored with a first weight strip and planted strongly in the substrate; the new “clump” of branches will quickly root and end up being a new total plant.

When a branch breaks off several new branches will grow out from the leaf nodes, making the plant thicker each time it is broken or clipped. If you pick to clip the plant, cut the branch near a set of leaves, as roots grow from the node where the leaf links to the branch.

4) Aquatic Plants from Bulbs

Bulbs can be dried from some fish tank plants and planted. Dry and dead, under the substrate. When planted and underwater, these “bulbs” will rapidly sprout and grow very fast under the right conditions. The Madagascar Lace is a prime example of this type of aquatic plant. These plants, also available in fish tank shops from time to time, are simple to grow, and can be and very appealing.

One disadvantage is they have a guaranteed season. They will grow and put out leaf after leaf from the base at a central core until lastly; they produce a flower of sorts in the center if the core. When a “flower” has been produced, the plant will enter into decrease and appear to die. The plant has not died, it is dormant; in nature, it would remain dormant through the dry season, storing its energy up until the next rainy season.

When you see this type of plant go into decline remove the “bulb” from the aquarium (often there will now be two or three bulbs when you dig it up from the substrate). Dry it and keep it in a cool dark place for at least three months. If there are several different bulbs, different them. Plant the “bulbs” the same way you did it initially and observe the cycle again.

5) Aquatic Plants that Propagate by Seed

Some aquatic plants propagate by seed; however, most are not real aquatics. Some undersea plants, like the Amazon Sword Plant in its lots of ranges, can outgrow the water or under the water. Just like the “bulb” type plants, this is nature’s way of ensuring that a plant will endure a cycle of wet and dry seasons. These plants cannot be propagated by drying and replanting seeds that eventually appear after a blooming stage; most of these aquatic plants recreate by sending runners.

6) Plants That Grow Both in and Out of Water

Some plants, like the Water Wisteria and Amazon Sword Plant, can grow both in and out of the water. When purchased in the shop, the majority of these plants will have big leaves and a firm thick appearance. When planted under water, a fantastic change happens: the leaves grow much more extensive and are laced with lovely flowing clumps.

In Europe, aquarists let these particular plants grow out of the top of the water, and again adjust to open air. They will grow up towards lights hanging 1 or 2 feet above the aquarium and revert to their “dry air” form. This provides an intriguing look with the “undersea form” of the plant within the fish tank and the “dry season” version of the plant thriving above the tank itself. Though this is not a favorite type of aquarium design in the United States and Canada, it is worth a look.

What Else You Need to Have Healthy Fresh Water in Your Fish Tank?

Other elements that guarantee your plant fish tank is the healthiest you can achieve consist of:

  • Complete spectrum lighting a minimum of 12 hours daily
  • Temperature must be in between 75-88 ┬░ Fahrenheit
  • pH between 6.5-7.4
  • 5 degrees KH (carbonate hardness)
  • 8 degrees GH (general hardness)
  • CO2 levels as high as possible, however lower than 40 mg
  • Low to absolutely no surface turbulence to help maintain CO2
  • 25% water changes every other week
  • Proper substrate for root growth.


Live aquatic plants belong in home fish tanks and the conditions that make fish tank plants grow and thrive make tropical fish delighted and healthy as well. Right essentials are all that is required: proper lighting, substrate, managed temperature, and healthy water conditions. To some hobbyists, live aquatic plants are almost as fascinating as the fish in the fish tank. So to a choose couple of enthusiasts, those who develop whole aquacultures and communities for their planted aquariums, the fish are merely the decor!
