What is the reason for the whitening of parrot fish
Usually, the parrot fish we see are red all over the body, or yellow or orange, but some fish friends will find that the parrot fish has turned white after they buy the fish and raise them at home for a period of time. What's going on?
1. Pigment is causing trouble.
The parrot fish was injected with pigment when it was with the fishmonger. When it came back, the pigment gradually disappeared, so the fish gradually turned white. Or the parrot fish bought can turn red by eating feed with lycopene from an early age. If you buy it without feeding it with red-increasing effect, the color of the parrot fish will slowly turn white.
2. Water quality is not well.
Raising parrot fish requires weak and low-hardness water, because blood parrots are born with a mouth that cannot be healed, and their Gill breathing capacity is reduced by half. Therefore, the respiration of the Gill has become an obvious "fatal wound"! Once the Gill is injured or the process of oxygen absorption is not smooth, it will directly affect the physiological health of the blood parrot, and the body color will fade temporarily. Therefore, raising blood parrots requires more than other fish to maintain better water quality and provide adequate oxygen.
3. Deterioration of water quality
The deterioration of water quality will also lead to the whitening of parrot fish, so raising parrot fish should especially reduce the dissolved nutrients in the water, keep the water clean and avoid a large number of bacteria and Gill diseases.
4. Severe temperature difference
For the species of blood parrots that are quite "sensitive" to temperature, the focus is not on the poor adaptability of the fish to temperature, but because in the case of low water temperature and drastic changes in water temperature, it is easy to lose bright body color due to physiological reactions. what's more, there will be black stripes or markings. Using a heater to raise the water temperature in the range of 2528 ℃, the fish can only show bright body color and full of vitality. On the other hand, the fish that live in low water temperature for a long time are not only in poor health, but also prone to illness and death.
