Trace elements needed for raising clown fish
Of course, to raise marine fish, there must be "sea water", and natural sea water is of course the most suitable for raising, but due to environmental pollution, it is not the most appropriate way to use sea water drawn from the seaside, and it is necessary to extract deep sea water from the open ocean. The sea water absorbed from the ocean must go through many treatment steps before it can be used. First of all, the containers for storing sea water must not use metal containers, because the ions of these metals will dissolve in the water, thus harming the health of the aquarium. Secondly, it should be sealed and stored in a place that is out of reach of the sun. after about a month, the dirt precipitated at the bottom of the container is filtered, and then irradiated by ultraviolet germicidal lamp, it can be put into the aquarium. Not everyone can do these steps, and inland areas are even more problematic; therefore, the use of "artificial seawater" is the most convenient way. Due to the results of long-term research abroad, the "artificial seawater" closest to natural seawater has been produced, which only needs to be dissolved in a certain proportion of tap water according to the instructions on the package. The best artificial seawater should have all the "major elements" (MAJORELEMENTS), "minor elements" (MINORELEMENTS) and "trace elements" (TRACEELEMENT) contained in natural seawater. The main elements are sodium, magnesium, calcium, potassium, sulfur, chlorine, etc., while the secondary elements include bismuth, carbide, silicon, iodine, lithium, fluorine, molybdenum, strontium and phosphorus, etc., these elements can make life in the sea long and healthy, maintain the original color in the natural ocean, prevent diseases and increase the chance of reproduction. Nearly 70 kinds of trace elements are of great help to the metabolism and water quality of organisms in the ocean.

Mud carp is a warm water fish. when the water temperature is 15-30 degrees, the mud carp have a strong appetite. When the water temperature is higher than 31 degrees, the mud carp lose their appetite; when the water temperature is below 14 degrees, the mud carps gather in the deep water area; when the water temperature is below 13 degrees, they stop feeding; when the water temperature is below 7 degrees, they cannot survive. Due to the poor cold resistance of mud carp, overwintering mud carp cultured in ponds in the Pearl River Delta are usually kept in deep ponds sheltered from the wind and sunny, and sometimes cold protection measures are needed. In the wild fish ponds in the mountains of northern Guangdong, it is difficult for mud carp.

There are seven tricks to improve the efficacy of internal administration of fish medicine.
First, the difference between prevention and treatment lies in the prevention of fish living in the water, the condition is hidden and difficult to detect. Once dead fish is found, the loss is great, and the treatment of fish disease is more difficult, which brings a lot of inconvenience. Therefore, we should actively implement the guiding principle of "no disease first prevention, early treatment of disease, prevention is more important than treatment", and establish the concept of prevention and drug application. Second, the skillful combination of traditional Chinese and western medicine in the treatment of fish disease has the advantages of long effect, few side effects and low cost of prevention and treatment. Western medicine has the characteristics of rapid efficacy and high cost. Practice has proved that it is effective.
