1. Genetic problems
Because the parrot fish is a female fish and a red fish in a purple fire mouth The artificial hybrid fish bred from the devil’s male fish, and the purple-red flamingo fish have black spots on the body surface, so the darkening of the parrot fish’s mouth may be caused by the genetic mutation of the combination of the two.
Treatment: If the gene mutation causes the parrot fish’s mouth to turn black, the owner does not need to take treatment for it, and there is no need to worry too much. Because this parrot fish becomes an adult, the black spots and black spots on its mouth or body surface will gradually disappear.
2. Bacteria infection
The blackening of the parrot fish’s mouth may also be caused by bacterial infection in the water. This is usually caused by the parrot fish attacking each other and hurting their mouths, and the water quality of the fish tank
is too poor, which leads to an increase in bacteria and germs in the water, causing mouth infections to turn black.
Treatment method: In this case, the owner should first observe whether the wound on the mouth of the parrot fish is serious. If it is only a slight scratch, the owner only needs to replace the water quality of the fish tank. The fish can return to normal; if the mouth of the parrot fish has festered, the owner needs to use a 3% concentration of malachite green or methylene blue solution to bathe the parrot fish. At the same time, during the treatment of sick fish, the water in the fish tank should be changed every three days to prevent the parrot fish from aggravating the disease due to unclean water quality.
3. Frightened
If The owner slaps the fish tank hard before feeding the parrot fish or the sound of the environment in which they are located is particularly noisy, etc., which will frighten the parrot fish. The parrot fish behaves the same after being frightened. Some of the body surfaces will fade, and some only have their tails blackened. And the blackening of the mouth is also one of the manifestations after they are frightened.
Treatment method: If this is the reason, the owner should transfer the frightened parrot fish to a quiet environment, and at the same time control the force of knocking the fish tank when feeding the parrot fish, so as to avoid the parrot fish. The fish are startled and then wait for them to recover on their own.
We remind: the problem of parrot fish’s mouth turning black can be big or small, and once the owner finds it, he should take a treatment plan in time. For more information about the blackening of parrot fish, please click “What’s the matter with black spots on parrot fish? “Continue to learn.
