Reasons Why Flowerhorns Losing Color

Flowerhorn might lose their color or look dull for many reasons. Some of the primary causes are:

Aging

As Flowerhorns age, they will gradually lose their color. This is due to a decrease in hormones and pigmentation as they get older. There is no way to prevent this from happening, but you can make sure your Flowerhorn is healthy by providing them with good water conditions and a nutritious diet.

Stress

Stress is one of the most common reasons for fish to lose their color. It can be caused by many factors, including adding new tankmates, incompatible tank mates, overpopulation, poor water parameters, excessive lighting, lack of hiding spots, a stomach infection, and more.

If your Flowerhorn is stressed, you will need to take steps to reduce their stress levels. This can be done by providing them with a peaceful environment, good water conditions, and a nutritious diet. You can get the following hiding spots and decor items:

Adding New Tankmates

Adding new tankmates can be stressful for Flowerhorns. If you add new fish to your aquarium, make sure they are compatible with your existing fish. You should also acclimate them slowly to reduce stress levels.

When adding new fish, you have to first quarantine the fish in a separate tank. In case it becomes sick, you might have to feed it with some medicines. Thus, test the waters before you add it up to the tank.

Incompatible/Abusive Tankmates

If you have incompatible or abusive tank mates, they can cause your Flowerhorn to lose color. Incompatible tank mates can be aggressive towards each other or bully your Flowerhorn. Abusive tank mates can damage your Flowerhorn’s fins or body.

Overpopulation

If you have too many fish in the aquarium, it can lead to poor water quality and stress. This can cause your Flowerhorn to lose its color. Be sure to keep the population at a manageable level and provide adequate filtration.

Poor Water Parameters

If the water parameters are not ideal, it can cause stress and lead to your Flowerhorn losing its color. Be sure to test the water regularly and make adjustments as needed. 

You can maintain the water parameters in the following manner:

the pH of the water 7.0 to 8.0 
The hardness of the water 8 to 20 dGH 
The temperature of the water 78 to 84 F (25 to 29 C)

Excessive Lighting

Too much light can be stressful for your Flowerhorn and cause them to lose their color. Be sure to use a light that is appropriate for your aquarium size and type.

Lack Of Hiding Spots

If your Flowerhorn doesn’t have many places to hide, it can cause them stress and lead to them losing their color. Be sure to provide plenty of hiding spots in the tank.

Stomach Infection

A stomach infection can be very stressful for your Flowerhorn and lead to them losing their color. If you suspect that your fish may have a stomach infection, consult with a veterinarian.

If the aquarium is too small, it can lead to stress and poor water quality – which can lead to your flowerhorn losing its color. Make sure you choose an aquarium that is appropriate for the size of your fish.

Poor Diet

If your Flowerhorn isn’t getting the proper diet, it can lead to them losing their color. Be sure to provide a balanced diet that includes both meat and vegetable proteins.
