Super delta bettas are single-tailed bettas with straight caudal rays, and a tail spread ranging from 130 degrees to over 170 degrees. Because they carry the same genetic resources as the Halfmoon line, they are also known as "Halfmoon Geno," "HMx," or "SDT." These are very beautiful fish and bring more joy to their owners than Halfmoon fish because there is no worry about tail collapse, fin erosion, or the fish having difficulty swimming and spawning.

If you're looking for information about this rare species, then you've come to the right place. In this blog post, we'll provide you with all the information you need to know on caring for super delta tail betta fish.

We'll explain what makes them different from other bettas, discuss their diet and water parameters, give tips on keeping your betta tank clean, and provide advice on breeding and selecting the best specimens.

1. What is super delta betta?

Super Delta Bettas are a modern line of Bettas; they are like an "upgraded" version of the Delta Fish, with the outstanding feature of a larger 130-degree tail spread, but still not reaching 180 degrees of a Halfmoon.

A standard super delta should have the following elements:

  1. The tail spread is greater than 130 degrees.
  2. Tail rays must be straight.
  3. The tails should be symmetrical about the body axis.
  4. The branching of caudal rays is at least three (branching three times).
  5. The trailing edge and the trailing ray must be perpendicular to each other.

With a super delta, the larger the tail spread (up to 180 degrees), the more beautiful it is considered to be.

2. Compare with Halfmoon betta

Because of their similar appearance, many people confuse the Halfmoon fish with the super delta-tail fish. The biggest difference between these two lines is the spread of the tail.

With a half-moon fishtail, it must spread 180 degrees (if larger, it will be an over-Halfmoon line). A super delta tail will allow for a spread from 130 to nearly 180 degrees.

Due to the stringent requirements of the Halfmoon fish, there are numerous Super Delta fish available today with a tail almost reaching 180 degrees that are mistakenly identified as Halfmoon.

As for other factors, such as color, fins, and size, a Super Delta can achieve the same state as a real Halfmoon.

This is a very nice tail form, and it is usually more fun than a Halfmoon. They also have more advantages because aquarists do not have to worry about some common diseases on Halfmoon fish such as tail collapse, fin explosion, or difficulty in spawning and swimming. Moreover, they are also easier to obtain and much cheaper than the authentic Halfmoon. An additional advantage is that they often produce several Halfmoon descendants if the brood comes from a Halfmoon line.

3. Size

The super delta tail betta typically measures between 2 - 3 inches (5 - 7 cm) in length from the tip of its head to the end of its tail, making it slightly larger than the average betta size. This species of a betta has become increasingly popular in recent years due to its distinctive appearance and vibrant coloring, which can range from bright orange and yellow to deep blues and purples.

The defining feature of this species is its large contoured caudal fin, which can stretch up to 3 inches (7 cm) across when fully spread out. This impressive finnage is what gives the super delta tail betta its name and helps distinguish it from other types of bettas. The caudal fin also has a unique "delta" shape to it, with elongated points that can resemble the wings of a seagull.

4. Lifespan

A super delta tail betta is a type of ornamental fish that can live for up to three years in the right environment. These small, brightly colored fish are popular among aquarium owners and require minimal care, making them an ideal choice for beginners. 

The maximum lifespan of these bettas is three years, but this can be shorter depending on the conditions it is kept. These fish prefer warm water with a pH level between 6.8 and 7.4, as well as plenty of oxygen-rich water movement throughout their habitat. They should also be fed regularly with high-quality betta food pellets or frozen bloodworms gave two to three times a week.

5. Colors and variations

Many pet owners have chosen to keep a super delta betta because of their unique patterning and vibrant colors. They can be found in shades of red, yellow, blue, green, black, white, and many more. These bettas are also popular due to their hardiness and ability to live in a variety of water temperatures and conditions. Besides, they are bred in many different variations such as the double tail, dumbo ear, and koi betta.

The double-tail super delta is one of the quite popular varieties with its wide fin structure that gives them an impressive appearance.

Dumbo ear super delta bettas are named after their large round pectoral fins that resemble the ears of a cartoon elephant, giving them a unique look among other betta fish.

Super delta koi betta has an oval-shaped body and long, full fins with vibrant coloration that mimics koi fish.

All of these variations are very popular and can make a great addition to any aquarium. They are hardy and resilient, making them ideal for both beginners and experienced aquarists alike. Each type has its own unique characteristics which makes them great friends. 

6. Female

In addition to males, female Super Delta Tail Bettas are also very popular. They have sharp caudal edges, good spread, well-proportioned bodies, and often very decent branching. However, if the tail span is not 180°, they are not female Halfmoons. A spread of between 150° and 170° is defined for most female Super Delta fish. These females usually make excellent stock, especially when used in crossbreeding with a Rosetail or Over Halfmoon male.

7. The behavior

Super Delta Tails require plenty of space in which to swim, so it is important to provide them with an appropriately sized tank for optimal health and happiness. They enjoy free swimming and are usually quite active during feeding time, often rushing around trying to get food before other fish do.

Besides, they are intelligent creatures and will often display interesting behaviors when interacting with humans or other fish in their tanks. As they become accustomed to their environment, they may even come to recognize their owners and show signs of pleasure when interacting with them.

8. Care

8.1. Tank size

When considering the size tank needed to keep a Super Delta Tail Betta, one should be aware that they do have special needs. These fish are quite large and require a bit more room than other betta varieties. Generally speaking, an aquarium of at least 3 - 5 gallons is recommended for housing a single super delta. This will provide enough space for them to swim around freely, as well as have plenty of water volume for filtration and temperature stability. It’s also important to note that these fish can reach lengths of up to 7 cm in length, so any tank smaller than 3 gallons would not be suitable.

Additionally, you may want to consider investing in some quality heating equipment. Since these fish are quite large, they need to have their water temperature maintained at around 76-78°F in order to remain healthy and happy. In addition to proper heating equipment, you should also make sure that the tank has plenty of places for your betta to hide and explore. Adding live plants or decorations will provide a natural environment where your betta can feel safe and secure.

8.2. Food & diet

Proper nutrition is essential for raising healthy, vibrant super delta tail bettas. A balanced diet contains proteins, carbohydrates, fats, and minerals. The main source of protein should come from high-quality fish food such as flakes or pellets specifically designed for bettas. These foods will often provide all the necessary vitamins and minerals to keep your betta in top shape. Additionally, you can supplement their diet with small amounts of live worms, brine shrimp, and bloodworms for a nutritious snack. Variety is also important when feeding bettas; offering different types of food every meal helps keep them interested and makes sure they are getting all the nutrients they need. 

It is also important to be mindful of feeding frequency; overfeeding can cause nutritional deficiencies as well as bloating and swim bladder diseases. Feed adult bettas no more than twice a day, providing them with only enough food that they can consume in two minutes. Juveniles may require up to three feedings per day, but reduce the amount of food accordingly to prevent overfeeding.

8.3. Water parameters

Water parameters are essential for raising healthy super delta tail bettas. Super delta tail bettas thrive in water that’s slightly acidic, around 6.5-7.0 on the pH scale, and at temperatures between 75-82 degrees Fahrenheit (or 24-28 degrees Celsius). To ensure the optimal health of your betta, weekly water changes should be done with an appropriate de-chlorinator to remove chlorine and other contaminants from the water. When doing water changes, Please make sure that the temperature of new and old water match as closely as possible to minimize stress on your fish. Additionally, an aquarium heater may be needed during cooler months to keep the tank temperature consistent. 

It is also important to test the water regularly for ammonia, nitrite, and nitrate levels. Levels of all three should remain low (ideally undetectable). If they become elevated, perform a 25-50% water change immediately to reduce the stress on your fish. Adding live plants can also help keep these levels in check by removing toxins from the water.

8.4. Tank Mates

When it comes to picking tank mates for your super delta tail betta, you should choose carefully. Bettas are territorial and can be aggressive towards their tankmates, so it is important to choose fish that won't stress or threaten the betta. Fish with similar temperament and size range are generally best suited. Small schooling fish such as Neon Tetras, Harlequin Rasboras, and White Cloud Mountain Minnows are all good options, as they typically live peacefully in groups of five or more and don’t usually compete with the betta for food or territory. If you have the space, small snails like Nerite Snails and Apple Snails can also make excellent tank mates, as they won't bother the betta and can help keep the tank clean. Finally, non-aggressive bottom feeders such as Corydoras or Plecostomus Catfish can also be good options for a super delta tail betta. These fish tend to stay at the bottom of the aquarium, so there is less competition for food and space with the betta.

In conclusion, the Super Delta tail betta fish is a beautiful, unique species of fish that deserve all the love and care we give them. While they may not be the easiest to take care of, their striking beauty and endearing personalities make them well worth the effort. As is true with any pet you keep - do your research first so that you’re ready for anything. If you’re interested in adding one of these special animals to your aquatic family, remember to always prioritize their health and well-being - it should be your number one priority! Nutritious food, appropriate tank mates, and an adequate environment will ensure a long and healthy life for your little friend. Did I miss something?
