CATDOLL : CATDOLL: Tropical fish breeding methods and precautions

1. Tropical fish breeding methods and precautions

How to breed tropical fish: When breeding tropical fish, they need to be provided with suitable breeding space and need to be fed regularly; Note: Tropical fish have strict requirements on water quality and are particularly sensitive to temperature changes. Most of them can adapt to water temperatures of 20-30 degrees. It is difficult for most tropical fish to survive outside this range.

Tropical fish are born in tropical waters, and tropical fish are divided into freshwater tropical fish and saltwater tropical fish.

The hometowns of tropical fish are mainly in Southeast Asia, Central America, South America and Africa. Among them, the Amazon River system in South America produces the most species and the most beautiful shapes, such as the Angelfish, which is known as the queen of tropical fish. There are also many species of tropical fish in Malaysia, Indonesia, Sri Lanka, Thailand, Myanmar and other countries.

2. Simple methods of raising tropical fish

My mother raises tropical fish, using an oxygen pump and a heater. The heater is adjusted to the temperature required by the tropical fish. The water is changed when it is dirty. The fish are fed once every morning. It is also necessary to observe whether the fish are pregnant. When the fish are about to lay small fish, the tropical fish are placed in a separate container to prevent the small fish from being eaten by the big fish, and to prevent the pregnant fish from eating the small fish when they lay small fish!

3. Why can’t tropical fish live in fresh water?

Generally speaking, the salt concentration of seawater on Earth is 16-47 (usually 35), while the salt concentration of fresh water is only 0.01-0.5, a huge difference between the two.

The salt concentration in the body tissues of marine fish is much lower than that in the seawater outside. Since there is a lot of salt in seawater, it has a high specific gravity and density. According to the principle of osmotic pressure, the water power in the body tissues of marine fish will continue to seep out from the gills and body surface. In order to maintain the water balance in the body, marine fish have to swallow a lot of seawater to make up for the water loss in the body. However, due to swallowing large mouthfuls of seawater, the salt entering the fish body has also greatly increased. In this way, in addition to excreting some salt from the kidneys, marine fish mainly rely on the "chloride-secreting cells" in the gill tissue to complete the task of salt excretion. In addition, there are also some marine fish, mainly cartilaginous fish, such as sharks, which store the metabolized nitrogen compounds in the blood in the form of urea, which increases the blood concentration and the osmotic pressure becomes equivalent to that of seawater. In this way, there is no problem of swallowing water and excreting salt.

Because tropical fish live in places with relatively high salinity, they cannot adapt to freshwater areas!

The soil and water quality of tropical fish are quite different from the freshwater inland areas, so it may be difficult for them to survive in a new environment.

Yes. People in cities use tap water to raise tropical fish. It is basically neutral water. Its hardness and pH meet the requirements of raising tropical fish, so there is no need to worry too much about this. However, when tap water is used to raise tropical fish, the chlorine must be removed. The main methods are drying and chemical methods. The drying method is to dry it in the sun for two days, or in a dark place for 4 to 6 days before it can be used. The chemical method is to use sodium thiosulfate to remove chlorine. The ratio is to add 1 gram of sodium thiosulfate to every 10 kilograms of water. After stirring and dissolving, it can be used. Found on the Internet.
