Types of Betta fish: The most popular, plus photos!

Are you thinking of pet fish? Having a full-fledged aquarium in home with colorful fish moving around is one of the pleasant things that you might get to see amidst your busy schedule and other responsibilities. People like you who are fond of keeping fishes at home, might want to consider having Betta fish in different hues and textures.

There are over 30,000 different kinds of Bettas, but only a few of them are suitable to keep in aquariums at home. These different varieties are classified on the basis of color, texture, tails and natural behaviors. Here we’ll discuss some of the most commonly preferred types of these fish based on their tail types, which you may consider for your home or office. The following types are only the most popular, there are many more. These are variations of Betta splendens.

1. Veiltail Betta

These are one of the most common Betta type in the world, particularly found in the United States these days. The tail is asymmetric and broad at the base, which becomes pointed towards the outer edge. This type is known for its jewel-bright spectacular fins and colors. Genetically speaking, the veiltail trait in Bettas is dominant over the short fins. The Male Veiltail Betta is susceptible to attack similar-looking fish. Thus, it is always advised to have only male veiltail in the aquarium with plenty of planets and little current.

2. Halfmoons

As the name suggests, the Halfmoon Betta appear shape of a halfmoon with large tail. The angle is the rays spread from 170° to a perfect 180° tail span. This variation in the tail section is one of the most beautiful, yet fragile part of this type of betta fish. The stronger the rays, the more support the tail gets during spreading.

3. Delta and Superdelta

The Delta Betta fish have a long-finned tail. The tail of this form of Betta is symmetric, triangular shaped and exhibits long rays. The superdelta tail spread is between 160 to 179 degrees, and often has rounded edges. On the other hand, the Delta tail is broad at the basis and widens towards the end.



4. Roundtail

As the name suggests, this type has a round appearance. This tail type is often seen in combination of Delta, Halfmoon and Superdelta Bettas.

5. Crowntail

Crowntail’s rays extend beyond the tail edge, which appears like a crown. The amount of rays that extend depend upon the genetic predisposition of the fish. The Crowntail gene is intermediary inherited. In clear words, the Crowntail carriers often show more or less extended rays beyond the edge of the tail. This type is known for its stunning tail with long fringes. The color of their tail and fringes comes in a wide range of colors and vary from single or double ray patterns. It should be noted that, female Crowntail Bettas have shorter fins than their male counterparts.

6. Plakats

Plakat tail type describes the short-finned type. It is originally found in Betta Splendens. The short finned fish makes it very hard to distinguish between male and female, especially with young ones. Most of the times, lack of knowledge and experience can get you confused from separating a male from a female one.

7. Doubletail

This tail type has a few typical characteristics. These include:

The caudal is made with two lobes and the dorsal of the Doubletail has twice as much rays than normal Singletail ones. Slightly shorter body length compared to other types.

The ideal Doubletail has two equal and symmetrical tail lobes with a nice split. This doubletail trait is often found in all Bettas, but their tail type and shape depends on the sum and variety of their genetic calculations. The double tail gene is intermediary inherited, which clearly means that Singletails carrying the Doubletail gene show a bigger dorsal which gives a fuller appearance.

So next time you see a Betta fish, try to keep in mind an overview of  all these characteristics and decide which type it is. Remember that it is hard even for professionals to distinguish between the different types and their gender. There is plenty of color choice in all these tailtypes. A thorough research on each of these different types will also help you make the right decision, as the natural behavior of each one of them differs and it is important to make sure that you maintain peace in your aquarium by making the right choice.
