CATDOLL : CATDOLL: What is the normal water temperature for freshwater fish activity?

1. What is the normal water temperature for freshwater fish activities?

It is difficult to say that freshwater fish are divided into tropical freshwater fish and temperate freshwater fish. 20-30 degrees is the most suitable for tropical freshwater fish. 15-25 degrees is the most suitable for temperate fish.

2. What is the normal water temperature for freshwater ornamental fish?

35 degrees? ? That's ridiculous. The heating tube can only heat up to 34 degrees at most.

1. The temperature of cold water fish can be between 18 and 23 degrees. When the temperature exceeds 30 degrees in summer, it needs to be cooled down.

2. Small tropical fish, such as peacocks, neon lights, etc., 20-25 degrees

3. Medium to large tropical fish, such as parrots, arowana, etc., 28-30 degrees.

It is recommended that no matter what kind of fish you raise, the temperature should be kept above 20 degrees to allow nitrifying bacteria to reproduce. If the temperature is too low, nitrifying bacteria will stop reproducing.

3. What is the growth temperature of catfish?

catfish

Catfish species are distributed almost all over the world. Most species live in fresh water such as ponds and rivers, but some species live in the ocean.

Generally, there are no scales on the body, but a flat head and a big mouth. There are several long whiskers around the mouth, which can be used to distinguish tastes. This is its characteristic.

That is the standard water temperature.

4. What temperature do tropical freshwater fish need to survive?

The water temperature for tropical fish is generally between 20 and 30 degrees Celsius. However, different types of tropical fish have different requirements for water temperature. For example, guppies, red swordfish, black Mary and other fish species can tolerate water temperatures of around 10 degrees Celsius without dying, while swallow fish, tiger barbs and other fish will die when the water temperature is below 18 degrees Celsius. Most tropical fish are very sensitive to water temperature. If the water temperature changes by ±2 degrees Celsius, they will catch a cold. If the water temperature fluctuates up and down for a long time, the fish will suffer from various diseases. Therefore, the water temperature should be kept constant as much as possible. The water temperature should not be too high. If the water temperature is high, the fungi in the water will multiply too fast and affect the water quality. The normal temperature for most fish to live is between 20 and 24 degrees Celsius, and the breeding water temperature is between 25 and 28 degrees Celsius. There are two common ways to control water temperature, which are natural control and artificial control.

Natural control is to place the fish tank in a sunny room, so that the fish tank can receive sunlight to increase the water temperature. The water temperature change of a small fish tank is relatively small. On the contrary, the small fish tank has less water and the water temperature change is large. If the room conditions allow, it is better to make the fish tank as large as possible.

Artificial control of water temperature mainly uses heating measures such as stoves, kangs, and heaters to heat. In recent years, the market has seen an increasing number of electric heating appliances, which is a better heating method. Most products have automatic temperature control functions and should be preferred.
