Do Betta Fish Change Color? (How & Why)

A betta fish’s natural color is usually a pale olive or green, but they can change colors to show their mood or to blend in with their surroundings.

There are many reasons why a betta might change color, but the most common reason is metamorphosis. Other reasons include feeling threatened, being sick, or breeding.

How To Change Betta Fish Color

Betta fish are a popular pet fish in the United States, but many people are unaware that betta fish can change color.

The process of betta fish changing color is called “metamorphosis.” In general, bettas will turn a brighter shade of green as they reach maturity.

Sometimes they will also change colors along the body, and some individuals may even change their stripes pattern.

This process starts with the male betta developing a large red dot on its forehead. Gradually, the dye spreads to cover his body and fins until he is an entirely new fish.

While changing color is fascinating to watch, it’s also an essential part of the betta’s life cycle.

It’s a unique and desirable trait.

Why Do Betta Fish Change Color?

Betta fish are popular in the aquarium hobby for a reason. They are hardy, colorful fish that make great additions to any home aquarium.

However, betta fish can also be prone to changes in color due to stress, illness, aging, puberty, and growth.

Here are some tips on how to monitor and care for your betta fish during these changes:

-If your betta fish is showing signs of stress or illness, consider adding more plants and rocks in their aquarium to provide additional hiding spots and areas to swim.

-Aging betta fish may start to show yellowish or greenish discoloration on their fins and bodies. This is natural and should not be treated with chemicals.

-Puberty can cause a change in the color of a betta’s scales and its fins.

Betta fish can be a beautiful addition to any aquarium, but they need the right conditions to thrive.

Here are some tips to help improve the color of your Bettas: 

-Feed them a healthy and varied diet. Bettas love pellets and live plants, so make sure to give them both in their food. A good diet will include small pieces of meat or other seafood.

-Keep their tank clean and clear. A dirty tank will lead to poor water quality for your Betta, which will affect their color and health overall. Make sure to do monthly water changes and keep any debris out of the tank.

-Avoid over-crowding your Betta fish tank. Overcrowding can cause stress for your fish and lead to problems such as decreased fertility or even death.
