The reasons why parrot fish are crowded in a corner of the fish tank:

1. The newly bought parrot fish are not adapted to the environment

After the parrot fish were just bought, they were put into the fish tank. The background of the fish tank Complete changes in the breeding environment such as color, lighting, sunken wood and other decorations, fish species, and surrounding environment may make parrot fish very frightened and cause them to lie down in the tank collectively and hide in corners with their heads down.

This is a normal phenomenon, just like the cats and dogs we have just brought home, they always need time to adapt to the environment, adapt to their owners, and gradually develop trust. As the feeding interaction is stably established and the conditioned reflex is established, this phenomenon will naturally resolve.

Believe in the power of feeding, humans die for money, birds die for food, and fish have a strong thirst for food. In fact, when people raise fish, the most important communication medium is food. Food will slowly strengthen the fish's memory. The person in front of it is the provider of food and can be trusted.

2. Water quality problems

This kind of problem often occurs in some breeding environments where the water is not changed for a long time, the water is replaced by supplementary water, or the nitrification system of the newly opened tank is not perfect. The understanding of water quality is relatively superficial.

At this time, key parameters such as pH, ammonia nitrogen, nitrite or nitrate in the fish tank may be abnormal, causing the overall condition of the fish to be poor. Generally speaking, it can be solved through water quality testing + water change.

If the water in the fish tank is not changed for a long time, the pH will decrease, and the color of the parrot fish may be very red. After the water is changed, the fish will temporarily lose color, but it can usually recover on its own.

3. Pressure from big fish

Don’t doubt it. Arowanas of forty to fifty centimeters, lucky fish, arapaima, lucky cat fish, etc. suddenly enter the tank. The parrot fish, which is about 20 centimeters long, has a strong sense of oppression.

Out of fear of unfamiliar big fish, parrot fish may choose to hide collectively, lying down in the tank, not daring to swim freely, to avoid attracting the attention of big fish and being killed in advance. This is the self-preservation of organisms. instinct.

In fact, many tropical fish can grow to very large sizes and have already experienced many battles. If they are too weak, they may have been killed by other fish. This kind of fish usually has its own domineering attribute.

In the world of fish, size often means powerful attack power. This kind of problem will generally return to normal as the mixed animals become familiar with each other.

4. Disease problems

External diseases such as white spot disease and saprolegnia, as well as internal diseases such as enteritis, can also cause several or all parrot fish to lie down in the tank. This This kind of case is not uncommon, especially white spot disease, which can easily make a tank of parrot fish lie flat.

If it is caused by disease problems, it is recommended to consult professionals to identify and prescribe the right medicine. Do not make random judgments or make random decisions on your own.

5. Water temperature problem

After the temperature drops below 20℃, the phenomenon of parrot fish turning white, lying down in the tank, and hiding in corners will be very obvious. This problem can only be solved by gradually increasing the water temperature. Work it out slowly.

Sometimes changing the water causes severe temperature rise in a short period of time.For example, the normal temperature of the fish tank is 28 degrees before changing the water, and it is 22 degrees after changing the water. This process occurs within 10 minutes. This huge temperature difference in a short period of time will make the parrot fish become nervous, uncomfortable, and become prone to lying in the tank. Hiding in corners.

Don’t think that parrot fish have strong skin and challenge the fish’s temperature tolerance at will. When a person is taking a bath, if a basin of cold water is suddenly poured over him, he will get goosebumps, so don't mess with your fish at will.

6. Turning on the lights suddenly

Many aquarists and fish keepers, if they do not have a fixed time to turn on the lights, will find that they suddenly turn on the lights in the fish tank or even indoors. Sometimes, parrot fish will also lie down collectively in the tank and hide in corners.

For fish, once they get used to the fixed light changes in a certain environment, suddenly turning on the light when it is dark will really scare them. It is not just parrot fish that does this, but many fish do this.

For example, the dragon fish may be frightened by the sudden light and jump around, and the tiger fish will also turn black in the corner.

7. Sudden noises

Fish are accustomed to the frequency of the environment and may be very afraid of sudden noises in some fish tanks, such as sometimes explosions of fish tank heating rods and water pump noises. It will cause the parrot fish to panic and hide in the corner without moving.

As the environment returns to normal, the fish will also return to normal.
