White Opal Betta fish are a stunning variety of Betta fish, easily recognized for their distinct silvery-white scales and shimmering iridescent hues. Originating from Thailand and Malaysia, these beautiful fish are members of the Osphronemidae family, also known as Labyrinth fish.

Unlike other tropical fish, Labyrinth fish have the unique ability to take in oxygen directly from the air due to a special organ. This means they can live in waters with low oxygen levels.

White Opal Betta fish can range in size from 2.5 to 3.5 inches (6.35 to 8.9 cm), and typically have an elongated body shape. They have large, bright eyes and their fins are long and flowing.

The coloration of their scales is what really sets them apart from other Betta species; they have a unique combination of silver and blue hues that truly make them stand out in any aquarium.

How much do White Opal Betta fish cost?

In today’s market, the cost of one white opal betta fish ranges from $20 to $25, depending on where you get it. Due to its rarity, a white opal might be difficult to find, particularly if you’re seeking a particular tail variation.

Ensure the health of the fish you buy by researching any pet stores or breeders before buying.

Typical behavior and temperament

White Opal Betta fish are known to be particularly energetic, playful, and curious. They love to explore their environment and find new hiding places and routes to swim. Their lively behavior is sure to add a spark of joy to your home aquarium!

These fish are quite social and can often be seen swimming with others of their kind. They are also known to be tolerant of tank mates of other species as long as the other species don’t bully or otherwise antagonize the Betta.

White Opal Bettas are relatively peaceful when it comes to dealing with other fish in the tank. However, they do display territorial behavior towards their own species, especially during the breeding season. To prevent fighting between male Bettas, it is best to keep one male per tank.

When kept in a healthy environment, White Opal Bettas will remain alert and active throughout the day. They can be quite interactive and fun to watch, making them an excellent choice for beginner aquarists!


The white opal betta has a beautiful opalescent sheen. It is a pure white fish. It is possible that they appear pinkish in color sometimes, possibly due to their scales revealing the betta’s skin underneath. The fish actually turns a very faint pink after a couple of months, however, according to some white opal betta keepers.

Despite being brightly colored, female bettas tend to be slightly duller in color than males, so they aren’t as commonly seen as males. In addition, their tails and fins aren’t large and ornate.

White Opal betta fish are some of the most unique and captivating species of betta fish.

They are prized for their striking, one-of-a-kind white and iridescent color patterns. If you’re looking to add a White Opal betta fish to your aquarium, it’s important to understand the particular needs and care requirements for this unique species.

First, White Opal betta fish should be kept in an aquarium that is at least 10 gallons. They prefer warm temperatures ranging between 75°F and 80°F, and water with a neutral pH level (between 6.8 and 7.4). Make sure to provide plenty of hiding places with decorations such as rocks and plants, as well as other equipment to make your aquarium more appealing.

Taking care of White Opal betta fish can be very rewarding if done properly. With the right knowledge and equipment, you can keep your White Opal betta fish healthy and happy for years to come.

Habitat, Tank conditions, and setup


The minimum recommended tank size for White opal betta fish is 2.5 gallons, but 5 gallons or more is preferable. Setting up the perfect tank for a white opal betta fish is essential to ensure their health and well-being. The tank should be no smaller than five gallons, although it’s best to go with a larger one if you can. It should also have plenty of hiding spots, like plants and rocks.

In addition, the water temperature should be kept between 78 and 82 degrees Fahrenheit, and the pH should stay between 6.5 and 7.0. You’ll also need to make sure to use a filter and keep the water clean.

You’ll also want to provide your betta with plenty of space to swim by adding some type of tank decorations or plants.

White Opal betta fish also require regular water changes of at least 25% every two weeks.

This helps maintain good water quality and helps keep your fish healthy. Additionally, you should monitor your tank’s parameters regularly to ensure optimal water quality.

Finally, if you plan on keeping multiple bettas in the same tank, it is important to remember that these fish are highly territorial, and they may fight with each other if given the chance.

Therefore, it is best to provide enough space and cover so that they can establish their own territories without intruding upon each other’s territories.

By following these guidelines, you can ensure that your white opal betta has a comfortable and safe home. Not only will this keep them healthy, but it will also keep them happy. With the right environment, your white opal betta can thrive for many years to come!

Filter and heating

When it comes to keeping white opal betta fish, providing the right filtration and heating system is essential. A filter helps to keep the tank water clean, and a heater helps to maintain a comfortable water temperature for your betta.

When selecting a filter for your tank, consider the size of your tank and the type of filter you need. Hang-on-back filters (HOB) are generally best for smaller tanks, while canister filters are often better for larger tanks. For best results, select a filter that can process three to four times the amount of water in your tank each hour.

Heating is also essential for white opal betta fish. Bettas prefer a water temperature of 78 to 82 degrees Fahrenheit, so a heater should be used to maintain this temperature range. When selecting a heater, opt for one with an adjustable thermostat so you can easily adjust the temperature as needed.

As with any electric equipment in or near water, make sure to use a waterproof submersible heater designed specifically for aquariums.

In addition, make sure to clean your filter and replace the filter media at least every three months to ensure optimal tank conditions. Regularly testing your tank’s water quality is also essential to maintaining healthy water conditions.


A good substrate is essential for your white opal betta fish to stay healthy and happy. For a natural look, many aquarists choose to use gravel or small river rocks. This type of substrate will provide a comfortable area for the fish to rest and hide.

If you want a substrate that is easier to maintain, consider using sand or one of the aquarium-safe sands available on the market. This type of substrate will keep the water crystal clear, and the fish will enjoy swimming and playing in it.

No matter which type of substrate you choose, be sure to rinse it thoroughly before putting it into your tank. This will help to remove any unwanted chemicals or dust particles that could potentially harm your fish. You should also check the pH levels of your tank to make sure they are appropriate for the fish before adding the substrate.


When it comes to caring for white opal betta fish, plants are a must-have addition to your aquarium. Not only do they add beauty and color to your tank, but they provide natural cover and hiding places for your betta fish.

The most popular choices for white opal bettas are aquatic mosses, Java fern, Anubias, and Amazon swords. These plants are great options because they are easy to maintain, hardy, and can withstand the higher temperatures that betta fish need to thrive.

When setting up the aquarium, make sure you create a safe environment with plenty of open space for your fish to swim around and explore. Aquatic mosses can be attached to rocks, driftwood, or even to the substrate of your aquarium.

Java fern and Anubias can be left floating or securely attached to rocks or driftwood. Amazon swords should be planted directly into the substrate. Make sure to not over-crowd the aquarium and provide adequate space between the plants so your betta has enough room to swim.

When choosing your plants, look for varieties that will thrive in the temperature of your aquarium and water conditions. You should also research if the species of plant needs any additional lighting or fertilizer in order to stay healthy. Properly maintaining your plants will ensure that they provide an ideal environment for your white opal betta fish.


It is important to understand the importance of proper lighting. Lighting is necessary for a betta fish to thrive, as it provides necessary warmth and helps them adjust their internal clock, ensuring they remain healthy.

White opal betta fish should be kept in an environment with moderate lighting. It’s important to note that betta fish don’t need direct sunlight – in fact, this could be damaging to their health. Instead, aim for around 12 hours of indirect light during the day, and leave the lights off at night.

When choosing lighting for your white opal betta fish, it’s important to consider the type of bulb you use. Fluorescent bulbs are the best choice as they provide a full spectrum of light.

This helps promote the production of essential vitamins and minerals, allowing your betta fish to stay healthy and vibrant. Be sure to avoid incandescent bulbs, as these can produce too much heat and be dangerous for your fish.

It’s also important to make sure your white opal betta fish have plenty of places to hide in their tank. This will help them feel safe and secure, especially when the lights are turned on. You can use plants, rocks, and other decorations to create places of refuge for your betta fish.

By providing your white opal betta fish with the right lighting, you can ensure they remain healthy and vibrant for years to come!

Are they good tank mates?

In addition to what we’ve already mentioned, do not place another male betta in the same tank with your white opal betta. The female would only be used if you were breeding, and that would only be for a short period.

Ideally, you should use a community tank of 8 to 10 gallons. Bettas do best in tanks with fish that aren’t aggressive or have bright colors or long fins.

It’s great to keep loaches, corydoras, and plecos with bettas since they are bottom feeders. Besides rasboras and croaking gouramis, you might want to consider Poecilias as well.

Angelfish, parrotfish, killifish, and Oscars should be avoided as tank mates. Whenever you decide which fish to add to your betta aquarium, be sure to do your research. Betta fish keepers can also find plenty of advice on message boards and forums that are dedicated to their hobby.

White opal betta fish diet

A protein-rich diet is necessary for white opals, as they eat larvae and insects in the wild. Their favorite foods are freeze-dried brine shrimp, bloodworms, and daphnia, but they can also eat flakes, pellets, freeze-dried, and live food.

To keep your betta healthy, you’ll want to avoid common flakes and look for special pellets and freeze-dried/live foods instead.

The amount of food you give your betta should not be more than what it can eat within a few minutes. You should try to remove threats from your betta if it seems disinterested in them.

If you overfeed your betta, the excess food will pollute your aquarium. Overfeeding can result in gastrointestinal problems for your fish.

White opal betta fish breeding

In order to breed the fish, you’ll need a breeding tank, which should be around 10 gallons without any substrate. It is imperative that you place the female betta in the breeding tank before introducing her to the breeding tank for about 30 minutes so that she can acclimate.

They will engage in a number of mating rituals when the male is with the female.
Males carry out the ritual by creating bubble nests, which are groups of tiny bubbles that stick together on the surface of the water.

It is interesting to note that a healthy male betta will build bubble nests even without a female nearby. Males wait for females under their nests before mating with them.
Upon laying eggs, the female will need to be removed from the tank and placed in her own.

It may take the male up to three days to care for the nest and hatchlings after the eggs are placed inside the bubbles.

You can begin feeding the fry when they are able to swim on their own. You should return the black opal back to its tank after they have started swimming on its own.

Keeping your fish healthy

Betta’s health depends on maintaining a clean tank and maintaining a balanced water parameter. Also, the water needs to be changed regularly, which is roughly 20% of the water every week if the tank is filtered. If it is unfiltered, it will need to be changed more often.

In addition to cleaning the filter and decorations, you should also maintain a healthy aquarium. Just make sure to avoid using soap when cleaning your pet. If you want to give these items a deeper clean, you can use distilled vinegar or bleach, but make sure to rinse them thoroughly before putting them back in the tank.

Make sure you watch your white opal betta’s color – if it turns pink, it could be experiencing a health issue. To ensure your betta stays healthy, you should ensure they have a healthy diet and maintain water temperature with a heater.
