The question of tropical aquarium fish, what aquarium fish is not a tropical fish

1. Freshwater fish

Tropical fish tend to need high temperatures to survive, while some freshwater fish can live in warmer environments. Therefore, freshwater fish is an important criterion for judging whether it is a tropical fish. For example, goldfish, koi, guppies, etc., are all freshwater fish, not tropical fish.

2. Cold-water fish

Contrary to freshwater fish, cold-water fish are not a category of tropical fish. These fish survive well in low temperatures and do not need high temperatures to live. Among the daily aquarium fish, freshwater freshwater Arowana, hardened fish, jasmine perch, etc. all belong to the category of cold-water fish.

3. Marine fish

Another important criterion for distinguishing tropical fish is whether they are marine fish. The environment required by marine fish is completely different from that of freshwater fish and cold-water fish, and they need a special seawater environment to survive. Tropical fish, on the other hand, do not necessarily need a seawater environment, as long as the water temperature reaches a certain height.

For example, flounder, angelfish, clownfish, etc., are all saltwater fish.

4. Special fish species

In addition to the above types of fish, there are also some special fish species that are not tropical fish. For example, wild carp and fish belong to wild aquatic products and do not belong to the category of tropical fish. These fish have some special requirements for survival and reproduction, and are very suitable for Bixian to grow and reproduce in a natural environment.

The stocking density of tropical ornamental fish has a lot to do with the size of the aquarium, the size of the fish, the equipment installed in the aquarium, and the ecological environment of the water body in the aquarium.

If the aquatic plants in the aquarium are vigorous, the oxygenation equipment is complete, and the water temperature is suitable, it is more suitable to put more ornamental fish, and vice versa. In the actual feeding process, in order to enhance the ornamentality, polyculture can also be considered.

Depending on the type and size of tropical fish, there will be some differences in the number of bait feedings. Smaller tropical fish should not be fed too much at one time, and can be fed according to the principle of eating less and eating more often; Pregnant females, juveniles and polyculture fish need to be fed according to the competition situation.

Put it in a place where water and air are abundant. The place is bigger, and it's better to put some greenery in the water. Keep it in a sunny place.

1. Water 1. Water quality.

All water in nature contains more or less different chemical compositions, and some chemicals will directly affect the growth and survival of fish, and tropical fish have higher requirements for water. Tap water, river water, well water, lake water, etc. can be used to raise goldfish directly, but they cannot be used to raise tropical fish directly, otherwise the fish will get sick and even die.

The so-called water quality mainly refers to the hardness and pH of the water.

The hardness of water is determined by the amount of calcium, magnesium, and iron salts in the water. It is divided into hard water, soft water and neutral water, and well water and spring water are mostly hard water; Tap water and river water are mostly neutral water; Rainwater is soft water. Neutral water should be used for breeding tropical fish, but although the pH of tap water in the city basically meets the requirements of tropical fish life, because the water plant often has to add some chemical disinfectants and purifiers when treating water, the water often contains Kang Mu Huan.

It is composed of three major BAI strains, namely temperate DU freshwater ornamental fish.
