Hangtai Aquarium: Why does red parrot fish turn white?

Parrot fish with its bright festive body color to get a lot of family love. Generally, the body color of parrot fish is red all over the body. However, some fish friends find that parrot fish in their homes will fade after a period of time, and the color will gradually fade into white or black. What is the reason for this? Does the change in body color prove that the fish is unhealthy? Today, let's learn about this common and annoying problem.

1. Pigment injection

In fact, not all parrot fish have gorgeous body color, there are quite a few fish born with lighter body color. However, many parrot fish were injected with pigment at the beginning of the business, and the pigment gradually disappeared after returning, so the parrot fish gradually turned white.

2. Feed

Some parrot fish can turn red by eating the feed added with lycopene from childhood, but fish friends buy it home and rarely continue to feed the original feed, so the body color becomes pale. To keep them, owners should buy feed that has a reddening effect, but choose chemical-free ones to avoid harming the fish's health.

3. Environment

When parrot fish first arrive in a new environment, they will turn white for a while. Don't worry, they will gradually change back when they are adapted.

4. Water quality

The parrot fish will become lighter in color within the first 2-4 hours of changing water, but will soon return to red. If fresh water is not added for more than 4 days, the parrot fish will also turn white in the environment where the water quality deteriorates. The mouth or gills of parrot fish blackening is a sensitive manifestation of poor water quality or incompatibility with water quality. Therefore, generally 2-3 days to change the water, a third or a quarter of a change. Keeping the water fresh ensures that the parrot fish does not fade.

5. Fish disease

Parrot fish are prone to two diseases. One is white spot disease, which may cause fading, and the color of some parts fades, or even turns white; the other is black spot disease, that is, the fish grows out of "black spots" and is gray. These two cases are more troublesome, if early, can be put into 1%-3% of salt, once a day, within 10 minutes; if to the middle and late, can be put in the jar of mercury, water becomes reddish, there is a good role in eliminating pathogens, but can not be used repeatedly, because mercury is toxic, fish is not easy to excrete. In addition, mercury nitrite is also a specific drug, but it is very risky to use this drug because fish are very sensitive to this drug and easy to cause death.

6. Temperature

Although parrot fish have strong adaptability to temperature, they are actually quite sensitive to temperature. Parrot fish are prone to stress reactions in low water temperatures and drastic changes in water temperature. Their body color will also turn white, lose their gorgeous luster, and even appear black stripes or stripes on their fins and tails. Therefore, the fish tank should be placed in a place where the indoor temperature difference is small, and it is best to keep the water temperature within the range of 25~28 ° C. The temperature difference between the water before and after each water change should not exceed 0.5 ° C. In addition, pay attention to warming and oxygenating the fish tank in winter.

7, frightened

Red parrot will appear after the scare fade or black spots phenomenon, after a period of time will recover. It is recommended that the owner should not mix it with large aggressive fish, knowing that parrot fish is a famous coward.
