Why Did My Betta Fish Turn White

Aquarium, Fish, Pet, Betta

There are four reasons betta fish turn white. Although some are natural, others result from the external environment. As such, you can fix them and retain the fish’s beauty. Let’s dive in;

  • They are stressed
  • They are aging
  • They are infected
  • They have sustained injuries

They are Stressed

Betta fish are very sensitive to the environment. And the main sign is becoming stressful. Once they are stressed, you’ll notice white patches on their fins or the whole body.

Conditions like temperature change can bring about stress. For instance, if you don’t have a good water heater, the temperature will drastically decrease, and the fish will turn white.

Secondly, a lack of a proper diet can bring about stress. Betta fish regularly need a carnivorous diet to stay healthy.

Third, they need well-filtered water and a spacious tank. If all these conditions are not met, the betas will be stressed and turn from their original color to white.

They are Aging

The average lifespan of betta fish is five years. However, a full lifespan is determined by feeding them a healthy diet and meeting all other requirements.

If the betta fish are kept in unhealthy conditions, you may notice the aging signs after only two years. Unfortunately, if the white color results from aging, it cannot be fixed.

They are Infected

Certain diseases and infections can lead to discoloration of betta fish. Infections like worms and parasites are notorious for causing white color in betta fish. Many people ask why is my blue betta fish turning white?

Here are some of the infections that lead to this unfortunate condition;

  • Fin rot – the fins look damaged with white patches. In some cases, they can turn purely white. If this disease is not treated earlier, it can rot the whole betta body. Fin and body cure powder medication can cure the infection if noticed early.
  • Ich – the infection is caused by a parasite known as Ichtyopthirius Multifiliis that settles around the skin. Usually, you’ll notice the fish are losing appetite and rubbing against the tank walls or other objects.
  • Anchor worms – are small worms in various colors that infect the external body. Normally, you’ll notice your betta fish rubbing against the tank walls. Secondly, you may see soles on their bodies.
  • Columnaris – It’s a bacteria that causes white patches on the betta fish body. Moreover, it can cause frayed fins and ulcers. Antifungal and antibacterial supplements like Bettafix added to food can treat columnaris infections.
  • They Have Sustained Injuries– Betta fish are highly territorial. As such, males are well known for fighting if kept in the same tank. On the other hand, females can attack each other too. After the fights, the results are injuries or even deaths. If they sustain injuries, you’ll notice the white color on the body due to stress and a sign of healing too.

Secondly, if the fish have been treated for infections like fin rot, the fins may remain white for some period as the healing process continues.
