Information on tropical fish, how to do this

Go and find out what you know about him and write it down.

Raise the fish in water before putting them in the tank. If you put the fish in the tank as soon as you buy it, your fish will definitely not live for a few days. Because the tap water used at home is poisoned and contains chlorine, it is not suitable for tropical fish to survive, especially the more delicate and expensive species.

After the fish tank is filled with water, don't rush to buy fish back, first turn on the water pump and run it for three to five days. Let the water in the tank be fully alive before considering releasing the fish in.

It is best to keep the water temperature of tropical fish at about 28°, and the temperature should not be too high or too low.

Students try to keep it at about 26 degrees, the density of fish is not too large, and you can raise some aquatic plants, these are all breeding methods.

1. How to get rid of the noise coming from the air hole of the oxygen pump? I folded the tube and felt much quieter, but the airflow was still there, so it wouldn't affect it, right?

There is a special gas volume regulator for sale, a few cents 1 piece. Controlling the air volume is more accurate and stable than manual bending.

2 I have a fish tank of about 25 liters, 20 small fish under 2 cm are polycultured, there are Mary, little fairies, traffic light peacocks. Is it okay if the water circulation filter is always on and the oxygen pump is turned on during the day and turned off at night? I opened it all day yesterday and closed it all night, and I woke up in the morning to see that the fish should be below and still below, and it was normal.

You raise a little too much, and as the fish grows, the density will increase, and being okay now doesn't mean being okay in the future. The temperature of water and dissolved oxygen are inversely proportional, so you should pay attention to the arrival of high temperatures in summer.

3. What is the approximate amount of feeding per day? A $1 coin area is tiled, more or less? Don't tell me it's hard to grasp the concept of eating in 5 minutes. Feed every day? Or is it enough to feed once every 2-3 days?

With your current feeding density, it is best to feed once every 1-2 days, and you can eat about 5 grains of 1mm pellet feed per piece. In fact, the time is very easy to grasp, feed it, and eat it up, leaving no bait for 5 minutes. For more than 5 minutes, I didn't want to eat the bait and didn't give it.

4When I bought a fish tank, they gave me a bottle of nitrifying bacteria, how often does this last? How often should I change the water in the fish tank? Is there anything else to add when changing the water besides sedimentation?

Just add the recommended dose according to the instructions, and if you don't even have the instructions, it's best to throw them away. The frequency of water change is generally based on the measured nitrite concentration, and it is estimated that you will not spend money for such a small tank with a test agent, and if your feeding density has enough magnetic ring in the filtration system, it is advisable to feed less food for 1 week for one-fifth. To change the water, it is necessary to dechlorinate the trapped water in advance, and change the temperature before changing.

5I have a small snapdragon in the bathtub, can't I add sterilized sea salt?

With or without this snapdragon, normal breeding of freshwater fish does not require salt. The argument of adding salt to disinfect is purely misleading. Qingwu's saline water can't directly kill germs, but it's enough to kill the fish.

Adding salt only makes it more comfortable for certain fish that are accustomed to living in high conductivity water, such as three-lake fish, soda fish, etc.

Finally, I would like to ask the gods, what kind of aquatic plants are better for these fish I raise?

Only the data of the tank can not give you the answer, some aquatic plants are not suitable for light is not good, and the grass is dead and rotten but bad water. It is recommended that you raise this goldfish algae first, if it can survive and grow, and then talk about how to enrich it.

Hemorrhagic rot disease is a bacterial infection.

1) Pathogen: bacteria. The route of infection is Daphnia or diseased fish and contaminated tools. This disease is not easy, and it is often a carrier after it is cured, and the water quality deteriorates and the disease occurs immediately, and the mortality rate is high, generally about 50.

2) Symptoms: Bleeding spots appear on the body of the fish, the fins turn from bright red hyperemia to pale and rot, and the gills also turn from red to white, and some of them are rotten. There are bleeding spots in the dissected viscera. It is often complicated by enteritis. The onset is acute, spreads rapidly (2 to 3 days), and is prone to cause a large number of deaths.

3)**: Fasting for 4 5 days, the whole box of antibiotic drug penicillin: 800,000 units of Xiangxiang 90 45 60 (centi) box, 1 in the morning and 1 in the afternoon, for 3 consecutive days as a course of treatment.

Generally, 4 days to take the bridge for 5 days can be **hall sensitive beating, the initial stage can be **, the middle stage can be controlled, and the rotten fins need about 1 month to grow. Pull out the aquatic plants in the sick box, rinse them with clean water, and disinfect them with Meilan (use a matchstick to dip them in Meilan crystals to change) for 15 to 30 minutes. Putting nitrofuracillin powder (1 5ppm) in the sick fish tank can be controlled in 3 days, and about 6 days**.

Salt of 0 5 1 can also be used at the beginning of the disease, which can also be controlled.
