How do you take care of a Crowntail Betta fish?

Your Crowntail Betta caring begins with the habitat. You may select a special tank relying upon which breed you intend to use as tank mates for the Crowntail Betta.

As a minimum, if you are not thinking of placing tank mates, we would like to recommend you use a 10-gallon tank. Any tank which is smaller than a 10-gallon tank may result in your Crowntail damaging its fins and crashing frequently.

If you are introducing a 10-gallon fish tank, then make ensure to alter the water at an interval of 2-3 days, however, do not destroy the useful bacteria by changing all the water in the fish tank quickly.

The natural atmosphere in South Asia is full of paddy rice fields, vegetation, and also slow-moving streams that naturally, filter the water. 

When it involves water in their tank, you would like to add Indian almond leaves in the aquarium. This can release a lot of use of natural acids for your Betta fish.

The Crowntail Betta is a smart freshwater species; also, they’re notoriously very active jumpers.

In fact, they will leap out from the fish tank to their death. Because of their jumping nature, there is a requirement to keep a well-fitted lid on your fish tank.

Lastly, the Crowntails, and Bettas in the usual sense, are labyrinth breathers. It means they are able to breathe oxygen from both the water and the air. 

This means you do not have to use any aeration systems in your fish tank. This can also protect your Bettas lovely caudal fins from turning into damage in the strong tank currents.

Habitat and Tank Requirements:

Tank Conditions

Your aquarium’s specific conditions for your Crowntail Betta play a very important role as it belongs to freshwater species. You must control three variable things inside your fish tank.

You’ll require staying within a pH level ranging from 6.4 to 7.0, with the water hardness of 2 – 5 carbonate hardness (dKh) and the temperature of water ranging from 76°F – 80°F.

With Crowntails you may require to keep a close observation of the tank’s water temperature. It’s very essential because it can make sure the Crowntail’s metabolism is perfect. Sudden movements or changes outside of +- 2°F of the recommended range may result in harm.

Tank-Tip: The light level conditions of the fish tank must be dim.

Using floating plants in your aquarium is always a very good addition; this can support your Crowntail to make a more natural habitat with the bubble nests.

As for substrate, a bare-bottom, fine sand, or gravel are always great for Bettas. As Bettas are able to replicate their traditional habitat, they are best suited to sand.

Compatibility and Tank Mates

The Crowntails are aggressive toward other species. Frankly, it is not to be mentioned as a friendly community fish!

The first rule is, the fish tank should not be overcrowded.

Bettas have their personal area and they always like to be territorial. As a rule, never introduce over a single Crowntail Betta male fish in an aquarium with another betta. The adult Crowntails can fight against each other until one dies.

They usually love to live alone; but, if you are planning to introduce tank mates, populate your fish tank and diversify, then you have some options.

Top-tip: Crowntail Bettas can fight with any other fish that shows its own behavior; aggression, territorial, dominance, and also larger in size.

If you emphasize compatibility then look towards fish breeds that love to swim in the fish tank’s different stratus. As Crowntails dwell in the upper and middle stratus of your fish tank, we are solely looking for bottom-dwellers that are calm and peaceful:

  • A good option is Neon-tetras
  • Guppies – they are really very fast and can get out of the Betta’s direction
  • Shrimp (e.g. Red Cherry  or Ghost)
  • Frogs (e.g. The African Dwarf Frogs)

If you are placing a Betta fish in an existing aquarium, do not introduce them into the fish tank directly.

Use a plastic cup or Betta cup, or, float on top of the aquarium for half an hour time with the Betta inside.

Observe how it behaves around the other fish in the aquarium. If your Crowntail Betta fish becomes overly aggressive (e.g. gills puffing) then it is not to be in your tank.

Once it is placed in the tank, you should ensure that the Betta isn’t overly aggressive to the other fish.

Diet and Feeding Requirements

The level of care and feeding needs for your Crowntail Betta may range somewhere from moderate to high. These fish are Carnivorous fish that requires a high-protein diet to survive.

As the fish have tiny stomachs you’ll need to serve them feed frequently in small portions. Three times per day is ideal but at a minimum of two times. Try to avoid large feeding sessions to feed the Bettas.

Generally, you’ll need to aim to give a maximum of 2 minutes’ worth of fish food to your Betta in each feeding session regularly.

So, you are overfeeding them; if it takes your Crowntail Betta more than 2 minutes of time to devour. Remove that food that your Betta has not finished within a 2-minute period of time.

A normal sign of overfeeding is that your Crowntail Betta will be constipated which will show a couple of symptoms;

1. Their eyes popping out of their head

2. Body of Crowntails looks swollen

Overfeeding may lead to a wrong nitrogen cycle and can make your Crowntail Betta fish constipated and ultimately sick, which is a big killer for the Bettas.

For all tropical fish, there should be variety in food which is always a decent factor.

Feeding them flakes, pellets, frozen foods, and live foods, are all smart options… providing they’re fed moderately. Bettas are a fussy eaters, therefore we’ve compiled their favorite meals, nutritious foods, and snacks for them;

Frozen Foods (Best for treats and snacks and not usual meals)

  • Brine Shrimp
  • Blood Worms
  • Black Mosquito Larvae

Live Foods

  • White Worms
  • Insect Larvae
  • Wingless Fruit Flies
  • Mosquito Larva


  • Betta pellets (2 to 3 pellets every feeding session)

In the wild environment, Crowntail Bettas are terribly hardy and can eat most food sources in their environment; as there are a few selections of food. Their usual diet in the wild consists of larvae, insects worms, and mosquitos.

Final note:

For optimum growth and vibrant colors of your Bettas, you may need to push a varied diet, full of high protein, and never prohibit fatty amino acids.

Crowntail Betta Breeding

As mentioned in the tank conditions section above, wherever you’ve got a Crowntail Betta you are probably to look at a bubble nest (i.e. clusters of bubbles) floating on top of the fish tank.

It shows a positive sign for two different reasons;

1. It indicates that your fish is healthy and strong enough.

2. It also can indicate that your Betta is currently getting ready for breeding

Their breeding method is exclusive.

Your male Crowntail Betta fish can build a bubble nest near the floating plants, in which the Crowntail Betta female can lay eggs and the male Betta fertilize later.

It can be expected to outlay over $2,000 for only a single spawn of Crowntail Betta fish and it’ll be vastly time-consuming…


The Crowntail Betta fish is susceptible to a few diseases which are very common to a large number of freshwater fish species. Most of those health issues arise from a poor feeding system and unsanitary or incorrect water conditions.


The disease Ich is known by its usual name of White Spot Disease. The Ichthyophthirius multifiliis parasite causes Ich, which is a protozoan creature that’s generally present in most freshwater aquariums, causing no issues to your fish until the poor water conditions or fish are weakened by sickness.

Ich is initially detected as a rash of small white spots across the body of the fish’s gills and fins. The affected fish usually clamp their fins, rub or flick against objects inside the fish tank, and can droop listlessly at the surface of the aquarium water.

Ich may be treated very easily with an over-the-counter treatment which you just add to the fish tank water. Simultaneously, increase the temperature up to 82o Fahrenheit for 4 days in order to disrupt the parasite’s lifecycle.

This double-pronged attack can kill the Ich parasite inside the aquarium and also on the fish.


The problem of constipation is generally caused by excessive feeding or by feeding the Betta fish an improper diet.

Your Crowntail Betta Fish might seem lethargic and swollen and they won’t want to eat any food. 

In general, fasting your fish for at least 48 hours permits the digestive system of the fish to process properly any food that is consumed by it. You can also provide a little portion of live food, which often helps to get things moving.
