Can I put plants in my betta tank?
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.

Do Bettas need live plants?
Bettas do need vegetation to replicate their natural habitat, provide hiding places and resting areas, mimic betta breeding conditions, 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 the size of the aquarium can accommodate it and 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 conditions as betta fish.
A leafy green plant known for forming dense carpeting layers, java moss is an affordable and low maintenance plant making it a great aquatic plant.
1: Java Moss
Java moss is slow growing and maxes out at 2-4 inches. Java moss is a freshwater plant that is capable of living in water from 60-80. Java moss can grow almost anywhere from driftwood to gravel, and even to the water surface.
- Suitable for all freshwater fish
- Common in breeding tanks as it is known to harbor infusoria
- Can be planted with others without endangering their growth

Betta bulbs are a great betta fish plant, in fact they’re even named for each other. Betta’s tend to like these because they have dense leaves perfect for resting, absorb betta waste, and keep the tank interesting.
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.
- Extremely hardy
- One of the best plants for betta
- Doesn’t need specific water conditions if its in a betta tank
- Don’t propagate as easily as other plants
Also known as Brazilian water weed, waterweed, and elodea, these are sturdy stemmed plants that are excellent for planting as a background plant or allowed to float.
The Anacharis plant is a fast-growing, bright green plant that has become a very popular plant among fish keepers. This plant is known to absorb excess nutrients, reduce algae growth, and filter toxins, making it a great addition to your Betta tank. And because of its lush growth and delicate leaves, it has become a favorite among plant-eating fish and snails.
The Anacharis can be planted or left to float, and since this species grows into thick “forests,” it makes a great hiding place and gives your Betta an excellent place to rest or sleep.

A staple in many freshwater aquariums, duckweed is adept at nutrient control, and easy to find at pet stores or even in nearby ponds.
Often confused for algae, duckweed grows in pods, with best growth occurring with a slow, gentle water flow.
TIPIf you choose to acquire duckweed from a natural source we strongly advise to wash it well with potassium permanganate and keep in a quarantine tank for at least 2 weeks before putting it in your tank to avoid the introduction of any parasites or diseases.
- Can grow in any depth of water, but deep water slows its growth considerable
- Widely used as a food source in community tanks
- Rapidly growing and can double its size every 3 days, earning the name of water weed
- Does not do well in well aerated environments such as those that have a strong filter or bubbler
Otherwise known as water wisteria, and native to India it can grow to a maximum size of 20 inches and requires at least a 10 gallon tank to be successful.
12: Hygrophila difformis
Generally found rooted in substrate, or spread across it like a carpet, water wisteria can provide a multitude of aesthetically pleasing effects to your tank.

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(especially if you have two bettas in one tank). 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:
- Hygrophila balsamica
- Water hemlock
- Water lettuce (contains saponins)
- Peace lilies
NOTEHygrophila 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.
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.
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.
