In the hot summer, raising a few lively and beautiful golden fish can not only beautify the environment, but also cool down the mood of the hot summer Not a lot. Nowadays, there are more and more people raising goldfish in the office. Most of the fish tanks in the office are not large. It is very easy to lack oxygen when raising goldfish in summer.

1. Precautions for raising goldfish in summer

1. Pay attention to the increase in water temperature:

The temperature in summer is generally 30-35 degrees, and sometimes 36 degrees The above high temperature is a very difficult season for goldfish with a suitable temperature of 20 degrees.

2. Dissolved oxygen coefficient in water:

Due to the influence of high temperature, the decomposition of various organic substances in the water is accelerated, and the dissolved oxygen coefficient is reduced. Phenomenon, at this time, we should be particularly vigilant about the two major threats of hypoxia and hot tail.

3. The timing of changing the water:

The timing of changing the water is to change the water twice a day in summer, before the sun comes out in the morning, and after the sun goes down in the afternoon, most of them are changed after the sun goes down water once. The amount of water exchange is generally controlled at 1/5-1/4 of the water body, and it is advisable to raise fish in old water.

4. Operation method of changing water:

In the method of changing water, first use a siphon to absorb the bottom residue and feces, and discharge 1/5-1/4 of the old water at the same time, and then add An equal amount of clean, oxygenated water that has been fully exposed to the sun. The operation of changing the water should be light, slow and steady to avoid damage to the fish, and it is not advisable to agitate the water in the pool. The container for raising goldfish should be brushed every 1-2 μL.

2. What should I do if the fish tank is hypoxic?

1. Temporarily stop feeding:

Do not feed the fish when it is hypoxic, because it eats food will increase the oxygen demand of the fish. If food is added, the lack of oxygen in the water will be more serious.

2. Food bait cleaning:

Clean up the garbage and food bait in the fish tank as soon as possible. Because the fermentation of these residual baits will increase the consumption of oxygen. This is not good for goldfish. To reduce the consumption of oxygen in the water, it is necessary to remove these fermented spoilage as soon as possible.

3. Replacing part of the water:

Do not change the temperature of the water sharply, replace part of the water for the goldfish, and the amount of dissolved oxygen in the water can be appropriately increased by changing the water. Protecting the life of goldfish is critical.

4. Install oxygenation equipment:

It is best to install a screening program (and with oxygenation function) for the fish tank, so as to keep the fish tank in place. A steady supply of oxygen prevents goldfish from experiencing hypoxia.

5. Avoid algal blooms:

In summer, the temperature is high, the algae in the pond grow vigorously, maintain a high dissolved oxygen in the water and inhibit the proliferation of phytoplankton, which is a An effective way to prevent goldfish from floating head and tail burn.

3. Emergency treatment of hypoxia in goldfish

1. Signs of hypoxia in goldfish:

If domestic goldfish sticks its head out of the water to breathe from time to time, it means that the water is in the water. Severe hypoxia, if no immediate measures are taken, goldfish will suffocate and die due to lack of oxygen.

2. Plastic Coke bottle:

After finding this phenomenon, you can find a large plastic Coke bottle or Sprite bottle, wash it with clean water, and put it in the bottle. Put more than half of the bottle of tap water for about two days.

3. Shake vigorously to add oxygen:

Block the mouth of the bottle with one hand, hold the bottom of the bottle with the other hand, and shake vigorously up and down with both hands for twenty or thirty times. Due to the continuous collision between the bottle wall and the water, the dissolution of oxygen in the water and the removal of harmful gases can be accelerated

4. The oxygen content of the water increases:

Then pour the water into the fish tank , the oxygen content of the water in the fish tank can be increased rapidly, so that the hypoxic goldfish can return to normal life. When the conditions are met, the method can be used to alleviate the hypoxia of the fish tank.

Fourth, indoor fish farming must know to prevent hypoxia

1. The fish tank should not be too small:

The fish tank should be larger than the washbasin, and the diameter of the tank should be the smallest More than 50 meters, the water should not be too deep, the diameter of the tank mouth is larger than the height, and the tap water contains chlorine. It should be dried for 24 hours and then injected into the fish tank. If conditions permit, it should be oxygenated for 24 hours and filtered for 24 hours

2. Control the feeding of bait:

Goldfish do not know whether they are hungry or full, so they should feed less and the frequency should be regular. It is best to keep four or five goldfish in an ordinary round fish tank at a time. At the same time, you should also be careful when choosing goldfish.

3. Through photosynthesis:

It is recommended to place some green aquatic plants in the fish tank to increase the oxygen content in the fish tank through photosynthesis, but pay attention not to be too much, because at night Plants compete with goldfish for oxygen.
