'why Is My Betta Fish Turning Black?'- What Are the Reasons?

The common causes of Betta turning to black are-

Temperature Changes

If the temperature of your aquarium water increases or decreases, you might find that your betta fish is becoming dark in color. It is because the change in water temperature affects the physiological functions of the pet. This also reduces its immune system forcing it to take in a dark color.

Genetic Factors (Marble Gene)

There are some betta fish breeds that have a genetic mutation which is commonly referred to as Marble Gene. This gene makes the bettas lose their natural color. If your betta has this gene, it may turn black in color due to its genetic makeup.

Inappropriate Water Conditions

Water quality is paramount in keeping your betta fish healthy. Poor water conditions may cause you to see black color bettas. This can be caused by either change in temperature or water pollution.

Repetitive Stresses

Bettas are very sensitive pets and even the slightest sound, movement, or anything that they find strange can cause them stress. Even their living conditions and tankmates may injure or irritate them. This makes them turn black in color. However, the intensity depends on how long the stressor has been going on.

Illness

The reason betta fish turn black can be because of being sick. Whether it is a bacterial infection or fungal infection, a disease, or a parasitic infestation, all these agents attack the fish's immune system.

Black spot disease is caused by parasitic infestation and can be treated with the help of a medicated fish food that you can buy from your local pet store.

Ichthyophthirius (Ick)

This affects the outer layer of your pet's skin and body making it look dark under the microscope. This disease is commonly called Ick and the best way to deal with this is by following a quarantine period of 30 days. This kills all the parasites while your betta fish rests in peace, without having contact with other fish.

Fin rot

When the fins of your pet turn darker colors it could be because they are infected with fin rot. The disease causes deterioration of the tissue in the fin, therefore turning them dark. It is important to check with your aquarium store whether the fins are infected or not before you start treating your betta fish.
