The Science Behind Why Some Betta Fish Are More Attractive Than Others

Bettas are known for their beauty. Their shimmering colors, intricate patterns, and flowing tails all make them quite the spectacle. But some bettas stand out from the rest when it comes to their looks. And that’s because some bettas are more attractive than others. While some species of betta fish are less likely to be chosen by pet lovers who prefer the more attractive varieties of the species. But why is that? What makes one betta fish more attractive than another? Let’s take a look at betta fish care and the science behind why some betta fish are more attractive than others.

What Factors Influence Attractiveness in Betta Fish?

As with many animals, the color of a fish is often the first thing we notice. And while some species of betta fish have more colorful or even fluorescent bodies, others are less colorful. The factors that influence a betta’s attractiveness are often based on several different factors. The formation of colors and patterns in the betta fish can greatly affect their attractiveness. Likewise, differences in tail shapes and extensions between bettas can also play a role in how attractive a betta is.

The Formation of Colors and Patterns in Betta Fish

When looking at the formation of colors and patterns in a betta fish, it can help to break the process down into three stages: genetic, chemical, and enzymatic. The genetic makeup of a betta fish is a combination of both the parents’ genes. In this way, a betta fish’s color is determined before it’s even born. Once the genes are activated, they create an enzyme called tyrosinase. Tyrosinase is what forms the pigment in the fish. Once the pigment is formed it becomes melanin, which is what colors the fish.

Differences in Tail Shapes and Extensions Between Bettas

Bettas with longer and more elaborate tails are often more attractive. When looking at why some betta fish have longer or more elaborate tails, it can again be broken down into three stages: genetic, chemical, and enzymatic. The genes of the parents cause their offspring to grow their tails in a certain way. When the parents have genes that are meant to grow long tails, the offspring will grow a long tail as well.

When the fish is born, it’ll form a protein from the genes. The protein is called beta-carotene hydroxylase. This chemical is what causes the change in the pigment of the betta. When beta-carotene hydroxylase meets with vitamin A, it turns the pigment blue. When it meets with vitamin E, it turns the pigment red.

The Importance of Body Shapes in Betta Fish

The importance of body shapes in betta fish is often something that goes overlooked. But as you’ve seen above, it can affect how attractive a fish is. Let’s break down the three stages that can affect a betta’s attractiveness based on its body shape: genetic, chemical, and enzymatic. When it comes to body shapes, the genes of the parents will affect their offspring. If the parents have genes that produce a large body, that’s what their offspring will have.

When it comes to chemicals, betta fish bodies are made up of proteins. Those proteins are created through genes. When it comes to proteins, have different shapes. Some shapes are more attractive than others. When it comes to enzymes, control chemical reactions between proteins. The proteins are what determine the shape of a betta’s body.


As you can see, many factors contribute to the attractiveness of a betta fish. The genes of the parents, the chemicals inside their bodies, and the enzymes that help those chemicals work. All of these factors play a role in making a certain betta fish more attractive than others. When it comes to choosing a betta fish, be sure to keep these factors in mind so that you can find one that you love.
