Do tropical fish need to cool down in summer?

The following are matters needing attention in raising tropical fish for reference.

1 If you plan to mix several different kinds of fish in a fish tank, you must pay attention to the compatibility between different kinds of fish. Fierce fish and docile fish can't be kept. There are too many individual differences to be mixed (temperate species can be considered); Different water quality requirements cannot be mixed, and so on.

When buying, energetic large and medium-sized fish should not only be inflated to keep oxygen, but also covered with black bags to reduce external interference to the fish. High-grade fish should be bagged separately to avoid injury caused by mutual contact. Pay attention to heat preservation when buying fish in winter. Plastic bags for fish must be thick and reliable, especially those with hard fins.

Don't put the tropical fish in the jar when you buy it. Soak the plastic bag containing fish in the fish tank for ten to twenty minutes before opening it, so that the water in the tank can flow into the bag for many times and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and quality. If there is a light, turn it off. In the dark, fish are quiet and not easily frightened.

Tropical fish are most suitable to live in the range of 24℃-28℃, and can live normally when it reaches 32℃ in summer, but if the temperature suddenly changes too much, tropical fish can't adapt. Therefore, before buying fish, you should not only adjust the water temperature of your aquarium, but also pay attention to the fact that the difference between the water temperature of your aquarium and that of your aquarium should not be large, which is generally allowed within 4℃. If the water temperature difference between the two is too big, I'd rather not buy it for the time being, and I'd rather make an extra trip to adjust the water temperature to basically the same before buying it.

A fish tank can't change too much water at a time, which will lead to water quality discomfort. Water quality includes pH value, hardness, chloride ion, dissolved oxygen, nitrate, sulfide, protein and turbidity. Tropical fish have adapted to living in raw water. If all the water is changed and the water quality suddenly changes, they will not be able to adapt, so their health will decline and they will get sick. If you need to brew the bottom and wash the tank, you should also keep most of the old water. After cleaning the water tank, the remaining water will return to the water tank, and then new water will be added.

Pay attention to the density of fish. Tropical fish like to have a large space for activities. Novices often buy the fish they like when they see it. They seldom consider how many fish can be raised in the tank, so they need special attention. Generally, it should be based on 1 raised water 1 cm long fish. If your fish tank is filled with 100 liters of water, it is safer to feed tropical fish with a maximum length of 10 cm. Individuals insist on 1.5 as the control target. In a larger space, fish are more active, stronger and brighter in color. Excessive feeding, high density, lack of oxygen in water and deterioration of water quality are the main reasons for the illness and death of tropical fish.

7 how to feed. The most important thing to see a fish tank is to control feeding, and it is advisable to eat once or twice every 3 to 5 minutes. Feed less in rainy days and not at night. Fish need to consume more oxygen when digesting food. The air pressure is low in rainy days and at night, and the dissolved oxygen in the water is also low. In this case, feeding the fish may lead to serious hypoxia in the water and kill the fish. Most dead fish occur at night, and severe hypoxia in water is one of the main reasons.

The bait must be clean, which is the easiest thing for beginners to ignore. Feeding unclean bait can easily lead to fish diseases. Although live food is the favorite of tropical fish, it should be put in carefully.

Keep the water clean. Tropical fish will consume a lot of oxygen, discharge a lot of waste, pollute water and breed germs after eating. In order to keep the water clean, a high-efficiency filter must be installed. If the fish are raised in a bare water tank, it is necessary to remove the educts from the bottom of the water tank and replace one tenth or a little more old water every day, especially in summer. The ecological tanks for fish and aquatic plants only need to change the water of 1/3 ~ 1/4 once a week. The filter can be designed with aeration, so that filtration and aeration can be carried out at the same time, which not only purifies water, but also supplements oxygen. However, the water tank cannot be inflated.

10 cannot bring grease and detergent into the water. Oil pollution will float on the water surface to isolate the air, so that the oxygen in the water can not be replenished, leading to the death of tropical fish due to lack of oxygen. Eating meat and even applying hand cream on your hands will bring oil into the water, so be careful to avoid it. Accordingly, fish tanks should be far away from places where oil and natural gas are produced.
