The main reasons for the discoloration of blood parrot cichlids to yellow are as follows:
Water Quality Issues: Blood parrot cichlids prefer weakly acidic water quality, with a pH value between 5.5 and 7. If the water quality is too hard or the pH value is too high, blood parrot cichlids will be sensitive to the water quality, and their body color will change, becoming dull or even turning yellow.
Water Temperature Issues: Blood parrot cichlids are tropical fish, and the suitable water temperature ranges from 25°C to 30°C. Excessive changes in water temperature or too low water temperature will cause stress reactions in blood parrot cichlids, making their body color dull, and they may even develop black stripes or spots.
Feed Issues: The feed for blood parrot cichlids may contain pigments that are not fully digested. These pigments accumulate in the fish tank, causing the water quality to turn yellow. In addition, improper selection of feed will also lead to a fade in the body color of blood parrot cichlids. It is necessary to choose feed with a color-enhancing effect to maintain their bright body color.
Health Issues: Blood parrot cichlids may suffer from diseases such as white spot disease or black spot disease. These diseases will cause the body color to fade or develop spots, affecting their appearance.
Solutions:
Improve Water Quality: Regularly change the water, keep the water quality clean, ensure that the pH value is between 5.5 and 7, and maintain the water temperature stably between 25°C and 30°C.
Select Appropriate Feed: Choose feed with a color-enhancing effect, and make sure that the feed does not contain chemical components to avoid harming the health of the fish.
Prevent and Treat Diseases: Regularly check the health status of blood parrot cichlids, and treat diseases promptly when they are found. You can add table salt to the fish tank for immersion or use specific medications such as mercurochrome for treatment, but use them with caution.
Avoid Scaring: Blood parrot cichlids are timid. Try to avoid walking around the fish tank or tapping on the fish tank to reduce scaring and help blood parrot cichlids maintain their bright body color.
