Natural Habitat And Origin

It is native to the Asian waters of Vietnam, Thailand, and the Mekong Delta. It mostly exhibits standing waters found in floodplains, canals, and rice paddies.

It found its way to the aquarium due to its aggressive disposition.

The fighting spirit of the fish enthused King Rama III of Malaysia. After collecting some of the fish, he gave a few of them to a man. The same man later gave them to a medical scientist named Theodore. One thing led to another until the fighting fish was finally named Betta Splendens.

Elephant Ear Betta Care And Tank Setup

Although betta fishes are known to be super hardy fish, you will still need to provide the right environment if you want to see your dumbo betta thrive. For a start, you should have a tank that is 20 gallons or more. Smaller tanks are likely to lead to health issues that may cause the fish trauma that could lead to its death.

Elephant Ear Betta Care And Tank Setup

Water temperatures of between 24 and 28 degrees Celsius or 75-82 degrees Fahrenheit should always be maintained. Aquarium heaters for the aquarium should therefore be available more so during cold seasons. You should also test and ensure the water has a neutral pH of 7.

Due to the extended flowing fins, you should choose smooth rocks that will not interfere with the flowing tails and fins. As the fish swims, rough rocks may tug at the tails and this could lead to fin rot which mostly affects aquarium fish.

Fine sand or substrate should be added at the bottom of the tank. Live hardy freshwater plants are a necessity to the tank too. Apart from adding to the beauty of the aquarium, plants also provide a sense of security to the fish. Remember to have plants without pointed extensions that will not interfere with the fish tail and fins.

Elephant Ear Bettas love to live in shallow water as they come with a labyrinth organ that enables them to breathe air on the water surface easily. 

Tank Shape

Like other species, Elephant Ear Bettas also prefer to live in a longer tank. One of the major reasons behind this is that in the wild, they are used to shallow water types. Besides, bettas always like to have wide territories. On the other hand, a longer tank will allow them to swim freely. Tall tanks are also good for the aquarists who prefer the horizontal space for aesthetics, viewing and aqua scaping. Don’t forget to add live plants, such as anubias, as well as floating plants to the aquarium. Most of the aquarists use large tanks for their bettas as offering more space you can lower the aggression level.

Marble Substrate: 

Some betta keepers prefer to use marbles to cover their tank floor. Well, this is not an ideal choice for the fish; using this, you can enhance the look of your fish tank. But remember that these substates can accumulate wastes and debris, and you will have to clean the water frequently. 

Soil Substrate: 

If you want to use live plants in your aquarium, then using soils can be a good option for you. However, to keep the tank water column clean, you may need to use secondary material, like gravel. As Elephant Bettas are labyrinth fish, soil can keep your fish healthy and happy. 

Gravel Substrate:

  • The male then wraps itself in a tight embrace around the female. This is referred to as “nuptial embrace”. Each time it does this, the female sprays eggs in the nests. This happens until there are no more eggs left.
  • The male then releases milt into the water to have the eggs fertilized.
  • The male then collects any eggs it considers to be sinking in its mouth to deposit into the nest. The female assists the partner but usually eats away eggs that it manages to catch.
