Why do discuss fish turn black?
There are several factors that can cause your Discus fish to start turning black.
1. Environment Adaption
Discus fishes can naturally change their color scheme in order to hide in their surrounding in a better way. It is an evolutionary trait that has helped this species to survive in the wild efficiently. Don’t forget that discus fishes are always at the mercy of predators in the wild, and therefore a good camouflage is their best defense. Blackening caused as a measure to adapt to their surrounding is nothing to worry about and is usually characterized by the development of black dots on the entire body known as “Peppering.” These dots can also grow to form patches.
2. Discus Stress
Discus fishes, just like many other species, are schooling fish and therefore prefer to be around their kin. This can cause a Discus fish that lives alone extreme stress, which can lead to blackening of the fish. That’s why it’s never recommended to have a single discus fish as they shine to their fullest when in a group.
3. Bacterial Infection.
One of the leading causes of blackening in Discus fishes is a bacterial infection. Bacterial infections can be seriously fatal, and therefore one should keep a lookout for such infections and attend to them as fast as possible.
You can prevent your beloved fish from such a bad outcome by strengthening their immune system; this can be achieved by providing them with a balanced, quality diet and providing them with clean water.
4. Marble Discus.
Having a marble discus in your fish tank will surely save you from worrying about blackening as this breed is naturally black and therefore is not susceptible to any blackening. This breed was developed in China.
5. Black-Stripe Syndrome
It is a condition in which a parasite present inside the body of discus causes granulation resulting in the blackening of the skin. A common parasite associated with this medical condition is called Cryptobia, which is a ciliated protozoan. Changing the water regularly and adding aquarium salt into the water can prevent your fish from such parasitic infections.
