Plants for Betta Fish

Top 7 Plants for Betta Fish

The betta fish, or Siamese fighting fish, is a hardy fish that prefer a lone status and ample growing space. Plants are fantastic additions to a betta fish aquariam that provide clarification and color to the water. Owners should make sure that the tank is plenty big enough to accommodate for these plants due to the growing habitat of the fish. Like many species of this type, they require warm water and a clean bowl on a regular basis. Additional foliage can also replicate a natural environment for fish that can add to longevity. There are several plants that can enhance their habitat to provide many years of enjoyment.


The anarchis plant can grow in both tropical and cold-water environments. They thrive particularly well in a moderately warm environment with a moderate amount of light. Anarchis prefers an alkalinity between 3-8 dKH and a neutral pH level. This plant is often called Brazillian Waterweed and provides a vibrant display of bright green leaves with shots of finger like projections from the leaves. The large leaves provide shade for the betta fish. The anarchis provide key contributions as one of the premiere plants for betta:

  • Nutrient control

Anarchis is one of the top betta plants that provide additional additional nutrients in the tank when other nutrients are depleted. The nutrient balance starts at preventing the growth of blue-green algae by releasing a substance that stops its growth. This creates a natural clarifying component to the plant.

  • Oxygenation

Plenty of oxygen is critical for non-tropical fish such as betta and other plants in the aquarium. The anarchis is a CO2-thriving plant. This means that additional CO2 fertilization can provide the necessary supplement to allow the plant to produce large amounts of oxygen in the tank.

This easy to care for plant is another moderate light bearing plant similar to anarchis in terms of the amount of CO2 fertilization and its ability to oxygenate the tank. The plant has very sturdy and dense foliage that provides a dramatic display in tanks. Hornwort can grow in temperatures from approximately 60 degrees Fahrenheit to almost 90 degrees Fahrenheit. The There are a few unique characteristics to this plant:

  • Wide range of acceptance for light

Hornwort can grow in less than ideal lighting conditions. The floating nature of the plant allows photosynthesis to occur more readily and provide a natural oxygenator for betta fish.

  • Fast propagation

Hornwort takes to the substrate in a take quickly and will spread just as fast. This may require additional maintenance to keep the needles from littering the tank below. It is considered the fastest growing floating plant for an aquarium.

Crypt plants come from the name Cryptocoryne. Don’t let the dark name crypts fool you. These plants are found in southeastern Asian waters in uncommon places and thrive well in most water environments with rich iron resources. These plants have some of the largest variety of sizes and shapes dependent on the amount of light received. They also come in red or green varieties that require the same tank fertilizers. Be sure to plant a strong iron-rich fertilizer at the base of the aquarium for this plant’s food. There are a few unique requirements to this plant that betta owners should be aware of:

  • Solitary plant lifestyle

Crypt plants usually don’t like competition from other plants. Many tanks have a large variety of various crypt plants as the sole betta plant of choice. When planted in groups, the crypt will become narrow and increase in height up to 6 inches. They also propagate by runners so care should be taken on the placement of the plants for foreground appeal.

  • Solid foundation

Crypt plants develop strong roots that provide their hardiness to the tank. This sturdiness requires a solid substrate and the ability to remain stationary at all times. Strong movement can cause the plant to collapse over time. This initial period of potential “crypt melt” will need to be monitored in larger tanks where water movement is more prevalent.

Asian Hygro

The Asian Hygro is one of the fastest growing plants for bettas on the market. They are also one of the most hardy and can survive fairly rough environments. The oval-like shoots add natural color to the aquarium and improve clarity of the water by naturally reducing many kinds of algae.


Eelgrass is also known as tapegrass or even wild celery. The ribbon-like leaves are thin and naturally flow with the stream of the water. The eelgrass is known as a submerged root plant. This means most of the vegetative mass is underneath the water. The plant provides a dense yet flaccid structure for a very natural habitat for fish.

Water Sprite

Water Sprite is more commonly known as the Water Fern or Indian Fern plant. This plant has been known as one of the most popular water plants for decades. The plant is very easy to propagate and grow. The plant can grow up to 2 feet in height and adhere to either a substrate or surface level of the tank. The amount of light in the aquarium will reflect how brilliant the green leaves become over time. The Water Sprite have some unique characteristics that differ form other plants:

  • Very robust growth rates

This plant has one of the fastest growth rates of any water plant. This can require planning for smaller tanks to avoid overcrowding the betta fish. Offshoots of the plant will break apart and form separate root systems over time. Pulling them from the parent plant can help extend propagation to other parts of the aquarium.

  • Preferencial lighting

Water Sprite’s love fluorescent lighting. They can, however, grow well under normal incandescent or direct lighting. Natural sunlight or fluorescent sunlight provide an additional boost to natural growth.
