Yes, in fact we encourage you to put vegetation in your tank to replicate betta’s natural environment and provide them with stimulation and enrichment. You can use either live or fake aquarium plants (or both) in your betta fish tank.

Plants in natural betta environment

Betta fish are found in rice patties, stagnant waters, marshes or ponds. As such betta fish are used to having a variety of aquatic plants to play and hide in. In fact, a heavily planted tank would make your betta feel right at home, and you’re sure to see them napping or building bubble nests on the leaves in no time.

Live Plants vs Fake Plants

There are benefits to having both fake and live plants in your betta fish tank, and there is really no right or wrong answer when choosing them. Below we’ve listed out a few pros and cons to each. Keep in mind that plants for betta fish don’t have to be all fake or all alive, you can provide a variety in your tank based on what you like. At the end of the day, the best betta plants are ones that you as the aquarium owner feel comfortable maintaining.

Fake Plants

ProsCons
✅Won’t die
✅Won’t grow any larger
✅No light requirements
✅No transport of pests or parasites from other places
✅Will not decay or foul the tank
✅Easily removed and cleaned
✅Little to no maintenance
❎Does not absorb CO2 or provide O2
❎Does not provide food sources
❎Does not absorb toxins

Live Plants

ProsCons
✅Absorb CO2
✅Provide O2
✅Harbors beneficial bacteria
✅Absorbs toxins
✅Food Source
✅Inhibits algal growth by reducing nitrates
❎Creates waste when decaying
❎Can carry parasites and pests
❎Has lighting requirements
❎Can cause O2 deficiency at night
❎Can look unpleasing if they are nibbled on

Do Bettas need live plants?

Bettas do need vegetation to replicate their natural habitat, provide hiding places and resting areas, and encourage exploration and stimulation. However, it is not necessary to have live aquarium plants in your tank. While having a live planted betta tank can be beneficial in producing oxygen, providing hides and shade, and keeping water conditions optimal they are not necessary.

Plastic plants can provide the same enrichment and stimulation benefits as live plants, but keep in mind that fake plants can have rough or sharp edges that can be dangerous to bettas’ fragile tails and fins.

What plants can you put in a betta tank

You can put many different plant species in your betta fish tanks as long as they have the same water quality requirements as your betta. As bettas are tropical fish any live plants that you put in your betta fish tanks should also be able to survive in tropical conditions.

It is also worth noting that betta fish are known to be jumpers, and as such their aquariums should be lidded. When choosing plants for betta fish you should avoid ones that grow above the water surface that could potentially loosen the lid.

What plants are good for betta fish 

When choosing plants for your tank ensure that they like the same light conditions and water parameters as betta fish.

8.: Betta Bulbs

Betta bulbs are made up of a variety of Aponogetons which are a species of flowering plants. The bulbs should be buried in the substrate 2-3 inches apart, because they’re fast growing we recommend planting 1 per 5 gallons.

Maintenance for your betta bulb is easy, they require the same conditions as your betta fish, however they should occasionally be “rested” or pulled out of the tank for a few months a year to replicate the dry season when they aren’t fully underwater. This will also help your tank replenish its nutrients and keep both your betta and bulb happy.

Pros

  • Extremely hardy
  • One of the best plants for betta

To propagate trim a few inches of stem with plenty of leaves off and let it float in the water, in a week or two the trimmed stem will begin to grow roots and soon you will have a plethora of baby plants. 

Pros

  • Fast growing
  • No issues with algal growth
  • Can help keep nitrate levels down

What plants do betta fish like

Betta fish enjoy large-leaved plants or thick vegetation. These provide shade within the aquarium and places for your betta to escape to. Within your betta tanks you should provide a variety of betta fish plants to ensure diversity for your fish. You can also observe your betta to see what kind of vegetation they like best. Often betta fish love floating plants or ones that rest on the aquarium floor.

What live plants are good for betta fish

Plants that didn’t make our list but still make fantastic betta fish plants include the pygmy chain sword plant, the banana plant, and Christas moss (which looks like mini fir trees!).

The banana plant is especially elegant and useful for creating private hides for your betta.

Do betta fish eat live plants

Betta fish are carnivores which means they eat a diet that mainly consists of meat. If you see your betta nibbling on live plants they could be bored, starving, or picking off microscopic animals that are attached to the plant surface.

A mistake that many betta fish owners make is not feeding their betta fish as much just because they have added an aquarium plant to the betta fish tank. Regardless of how much vegetation is in your tank you should still be feeding your betta fish.

What plants are toxic to betta fish?

The most important thing when questioning if a plant is toxic to betta fish is to check if it has calcium oxalate crystals, as they are the culprit of the poisoning. Calcium oxalate is an insoluble chemical (it doesn’t dissolve in water) that can cause digestive problems such as stomach swelling and irritation. This chemical can also cause problems in a fish’s central nervous system.

Plants to avoid include:

  • Pothos
  • Dieffenbachia
  • Hygrophila balsamica
  • Water hemlock
  • Philodendron
  • Water lettuce (contains saponins)
  • Bamboo
  • Peace lilies

NOTE

Hygrophila balsamica shoots are toxic upon emmersion from the soil, but the toxicity ceases once it assumes its submersed forms. Since most aquatic plant nurseries grow their plants underwater it’s difficult to determine whether this plant would be safe and it is best to avoid it altogether.

Watch this video below for more info on what plants to avoid with betta fish.

What Plants Should You Avoid with Betta Fish?

Should you use fake plants for betta?

Choosing whether to use fake or live plants is really a preference for each aquarist. Fake plants require less care and provide many of the same benefits as live ones when it comes to betta fish. The best fake plants are ones that have no sharp edges to ensure no harm comes to your betta. We recommend feeling the edges of the plant before you buy or using silk plants for betta fish.

Conclusion

In conclusion, adding vegetation to your betta tank will not only make it more pleasing but provide enrichment and other benefits to your betta, and any other aquatic life in the aquarium.
