Betta or Siamese Fighting fish has become one of the most popular ornamental fish kept and cultivated by breeders in recent times.

The flashy colors, iridescent scales, and beautiful-long fins that flow around it like an underwater ball gown are the fish’s hallmarks. Also, its aggressive attitude is something unique to be kept at home.

Caring Bettas are easier than many other types of fish. They are stronger, require less space, and can survive in water with lower oxygen content.

Even so, if you are interested in the health and well-being of your betta fish, you may follow the advice that placing betta fish in vase is not recommended under some circumstances.

Bettas need a house with at least 12-16 liters of space in a tank. The filtration and heater are also rarely provided in a Betta vase. Remember, they are tropical fish that need to be always kept above 23.5℃.

These are unideal environments that can make them die due to poor conditions. However, some people do have long-term success with Bettas vase. Find out how to set up if you want one!

If you decide to put betta fish in vase, ensure you do proper maintenance and care. They need filtration, proper temperature, vase cleaning, regular feeding, and enrichment like plants.

1. Select your vase or bowl and location

To keep your Betta happy and healthy, consider using a large glass flower vase so it has sufficient space that it can call its territory. The vase location is paramount, and you may want it to impact your Betta’s longevity.

Place it away from noise because it can cause fin rot and stress. Make sure to avoid excessive natural light as well, as it may promote algae growth.

Other than that, you will want to include gravel and a plant to put in the vase. As Bettas are jumpers, you must place a tray above the surface to keep Betta from jumping out.

2. Select your plant

You need to find out what kind of plant for betta fish vase. Make sure you pick the right plants that are safe and work well with them. Chinese evergreen and Java ferns are two underwater plants they like.

If you decide to use fake plants, pick one that doesn’t have any sharp edges. Moreover, if you want to set up a betta fish vase with a top method plant, Philodendrons and Peace lilies are the best choices.

3. Get everything ready

Now when you have everything prepared, it’s time to set up your Betta vase!

  1. Clean the vase or your bowl using hot water. Please do not use any cleansers or soap as they are harmful to fish.
  2. Remove the plant from its pot, wash the roots and clean thoroughly.
  3. Arrange the gravel on the bottom of the vase, then fill ⅔ of the vase with clean fresh water. To remove iron or chemical in the water, you may need a small amount of water conditioner for aquariums.
  4. Add your Betta. Let it acclimate to the water in the vase. Then place the plant roots. It would be best if you were sure that there is still plenty of room for your Betta to swim around.

Do not let the tank drop below 20℃ (68℉). It will be fine if you place them in a room that has these ranges of regular temperature. Otherwise, you will need to use a small heater.
