The main reasons for the black lips of blood parrot cichlids include genetic mutations, bacterial infections, and being frightened.
Genetic mutations: Blood parrot cichlids are a hybrid variety of the midas cichlid (Amphilophus citrinellus) and the red devil cichlid (Amphilophus labiatus). The midas cichlid has black spots on its body surface. Therefore, the darkening of the mouth of blood parrot cichlids may be the result of a genetic mutation. In this case, no special treatment is required, and the black spots will naturally disappear when the fish reaches adulthood.
Bacterial infections: If blood parrot cichlids attack each other and cause injuries to their mouths, and the water quality in the fish tank is poor, bacteria and germs will take the opportunity to invade, resulting in the darkening of their mouths. Minor abrasions can be resolved by changing the water, and it usually takes about a week to recover. If the mouth has already shown signs of ulceration, it is necessary to use a 3% malachite green or methylene blue solution for a medicated bath. At the same time, change the water once every three days to prevent the condition from worsening.
Being frightened: Blood parrot cichlids are very sensitive to environmental changes. If they are frightened, for example, by hitting the fish tank hard or due to excessive noise in the surrounding environment, it may lead to the darkening of their mouths. The treatment method is to transfer the frightened blood parrot cichlids to a quiet place. When feeding, tap the fish tank gently to avoid scaring them again and let them recover on their own.
Preventive measures:
Keep the water quality clean: Change the water regularly to ensure good water quality and prevent the growth of bacteria.
Avoid scaring: Pay attention to avoiding sudden noises and vibrations during feeding and daily care, and keep the environment quiet.
Observe changes in water quality: Regularly check the water quality indicators to ensure that the pH value and temperature are within the appropriate range and avoid large fluctuations.
Through the above measures, the problem of black lips in blood parrot cichlids can be effectively prevented and dealt with, ensuring the health and beauty of blood parrot cichlids.
