But, long-term exposure to unsuitable conditions can lead to diseases for your Crowntail bettas. You must provide their minimal requirements to keep these bettas healthy in captivity.

How Do You Take Care Of A Crowntail Betta Fish?

To take care of a Crowntail betta, you should know the process of tank set-up, basic supplies, water parameters, diet, etc. let’s start with a basic introduction to Crowntail betta tank set-up.

Tank Size For Crowntail Betta: What Tank Does A Crowntail Betta Need?

An adult Crowntail betta can reach up to 3 inches. For this reason, many experts suggest keeping a single Crowntail betta in a 5-gallon tank. When you add other necessary equipment and stuff to your Crowntail betta aquarium, a space of 5 gallons may fall short for your betta.

The ideal tank capacity for keeping one Crowntail betta fish will be 10 gallons (38 liters). If you want to add more tank mates for your Crowntail betta, the thumb rule will be adding 5-gallon space for each fish. 

If your Crowntail betta doesn’t move comfortably in its tank, it’ll become stressed. That’s why you must provide your betta adequate space. In addition, you must remember not to make the water level deeper than 12 inches for your Crowntail betta.

What To Keep Inside The Crowntail Betta Tank

To help your Crowntail betta survive in captivity, you should add some additional things. Besides, your Crowntail betta requires some essential equipment. Let’s see what to keep inside your Crowntail betta tank.

1. Substrate

It is not a must to keep the thing for the Crowntail betta tank. Since some substrates can change the pH of water, some owners do not like to add substrate to a betta tank. 

Keeping substrate in your Crowntail betta aquarium can house good bacteria over them. Not to mention, these good bacteria play a vital role in breaking ammonia, nitrites, and nitrate.

Besides, you can keep the substrate in your Crowntail betta tank for decoration purposes. Instead of setting up a bare bottom tank, adding substrate will make your Crowntail betta tank more aesthetic.

While choosing a substrate, you should ensure that the substrate should not change the mineral contents of the tank water. The most suitable option as a substrate will be gravel for your Crowntail betta. I’ll recommend Seachem Flourite Black Clay Gravel if you want to buy it for your Crowntail betta. 

2. Plants

One of the most significant additions to your Crowntail betta tank will be plants. Live plants will create a naturalistic vibe in the captive environment of the tank. Also, your Crowntail betta can take a rest and hide whenever it feels stressed.

Before adding plants, you should consider the lighting, temperature, and pH requirements for your chosen plants. Don’t forget to ensure that the plants are safe for your Crowntail betta.

You can add java fern, java moss, Marimo moss ball, Anubias, betta bulb, hornwort, white sprite, wisteria, cryptocoryne, floating plants, amazon frogbit, etc. 

Also, you can add fake plants instead of live plants. In that case, you should wash your fake plants with warm water before adding them to your Crowntail betta tank.

3. Filter: Do Crowntail Bettas Need A Filter?

Naturally, your Crowntail betta produces biological wastes in captivity. Moreover, the plants and leaves may fall off. The leftovers and fallen plants produce ammonia after decaying. For this reason, a filter is a must to keep the water parameters good for your Crowntail betta fish.

Besides, a good filtration system helps add oxygen to your Crowntail betta tank. By conducting mechanical, chemical, and biological filtration, a good filter works to clean the wastes. 

Despite adjusting a filtration system, you should do a regular water change to give your Crowntail betta fresh water. However, the experienced owners suggest a sponge filter for the Crowntail betta tank. In the case of a heavily planted tank, you can prefer a Canister filter. 

4. Heater 

You might know that Crowntail bettas are tropical fish. So, these Crowntail bettas require a range of 75-80 degrees Fahrenheit temperature to remain healthy. If the room temperature stays within the mid-70s range, you may not add any heater to your Crowntail betta tank.

Otherwise, you may find your Crowntail betta floating in the water dead due to cold temperatures. So, installing a heating system can save your Crowntail betta if you live in a cold country. You should ensure that the temperature range doesn’t exceed much of the ideal range. 

5. Lighting

In the wild, Crowntail bettas are found in murky water areas. Since the wild Crowntail bettas do not depend on natural lighting much, the requirement of lighting is pretty little. 

Your Crowntail betta requires lighting and darkness in their captivity. To maintain a good cycle of day-night, you should fix a lighting system in your Crowntail betta tank. It’ll help them stay active and playful.

Like other bettas, Crowntail betta fish also prefer darkness to have a sound sleep. If you want to match the sleeping pattern of your Crowntail betta with yours, you should turn off the lighting at your bedtime. 

Several beginners make the mistake of keeping the Crowntail betta tank directly at exposure to sunlight. The heat of the sunlight may warm up the water temperature. 

6. Decorations 

To make your Crowntail betta tank aesthetic, you can add some décor items. The décor items should be safe for your Crowntail betta. You should ensure that no décors should have sharp edges.

In the list of décor items, there is a betta hammock, Marimo moss balls, floating betta logs, a ceramic cave for an aquarium, hoops, etc.

7. Fitted Lid

You might be aware that bettas tend to jump out of the tank. In such cases, your betta can accidentally die. To avoid such a tragic incident, you must add a fitted lid to your Crowntail betta tank.

3 Water Conditions For Crowntail Bettas

The most significant rule to keep your Crowntail betta healthy is to maintain ideal water parameters. Since Crowntail bettas thrive in water, poor water conditions may risk the lives of your betta.

Many owners prefer to add tap water since it is a readily affordable source of water. But, local tap water may contain chlorine and heavy metal. If you want to add tap water to your Crowntail betta tank, you must treat the water with any suitable water conditioner. 

Bottled or spring water is also safe for your Crowntail betta. In the case of using distilled water, you should add minerals to the water. 

I’ve made a small list of water parameters for Crowntail betta below. Let’s check it out.

Temperature 76-80 degrees Fahrenheit 
GH3-4 dGH
Water Hardness2-5 dKH
Nitrate Less than 20 ppm
Ammonia 0 ppm

1. pH For Crowntail Betta

The pH range for Crowntail better is between 6.4-7. Many betta enthusiasts love to keep the water pH neutral. But, a few studies show that Crowntail betta does better in slightly acidic water. 

You should ensure that the water should not turn alkaline. That’s why substrate choosing should be perfect for your Crowntail betta tank.

2. Temperature

Since Crowntail betta is hardy fish, these fish can tolerate temperature fluctuations. The ideal temperature for these unique betta ranges from 72-86 degrees Fahrenheit. If the temperature range doesn’t remain optimal, your Crowntail betta will not happily thrive in the tank water.

While keeping Crowntail betta as pets, you should remain concerned that the GH and KH level should not increase much. These Crowntail bettas thrive best in soft water. Keep the water hardness within 2-5 dKH.

Tank Mates For Crowntail Bettas

Before choosing a tank mate for your Crowntail betta, you must know about the temperament of this betta with spiky tails. For details, you can check out this write-up: are Crowntail bettas more aggressive?

Crowntail bettas have a poor reputation for their highly territorial temperament. These bettas remain too aggressive to tolerate any other tank mate of equal size.

If your Crowntail betta is male, you should not add any other tank mates to its tank. Crowntail bettas are intolerable towards other Crowntail bettas too. These fighter fish may tear up their tank mates by bullying and attacking them. 

You can choose bottom-dwelling fish if you make up your mind to create a community tank. In the case of a female Crowntail betta, you can add multiple female Crowntail betta together in a tank. 

Diet: What Do Crowntail Bettas Eat?

The new betta owners often try to overfeed their Crowntail bettas. But, the stomach of these bettas is as tiny as their eyes. So, you need not feed much food to your Crowntail betta.

Due to being carnivores, Crowntail bettas rely on a protein-based diet. You can keep live foods, pallets, flakes, mosquito larvae, fruit flies, brine shrimp, and frozen foods for these bettas. Also, you can offer worms as an occasional treat.

In the case of baby and young Crowntail betta, you must feed them every day. On the other hand, you should feed your adult Crowntail betta every other day.

But, you must not overfeed your Crowntail betta. The excess food will rot at the bottom of the tank. Further, it’ll cause an ammonia spike.

The quantity of foods depends on the appetite of your Crowntail betta. You should notice whether your Crowntail betta finishes its food too fast or slow. You can reduce the amount of food if your Crowntail betta doesn’t finish the entire food. 

If you want some recommendations for your Crowntail betta, I’ll recommend Omega One Betta Buffet Flakes, New Life Spectrum Betta Fish Food, etc.

Breeding Care For Crowntail Bettas

Many betta owners love to experience the journey of having baby Crowntail betta from their pet parents bettas on their own. For this, you should take extra care of your Crowntail betta for breeding purposes.

Firstly, you should own female and male Crowntail betta separately. Introducing the female Crowntail betta in your male Crowntail betta tank can be a bit difficult.

Although the male Crowntail betta remains excited to breed, the female Crowntail betta may deny the male betta. Make sure that both bettas are sexually mature.

You might notice a bubble nest created by the male Crowntail betta in the tank. To encourage the buildup of bubble nests, you should provide a high protein-based diet to your male Crowntail betta.

After pairing up, the female betta releases the eggs. Afterward, your male Crowntail betta fertilizes the eggs. Then, it places them into the bubble nest for hatching. Don’t forget to keep the temperature range constant to ensure successful breeding.
