When raising Luohan fish, good fortune comes first, followed by emperors, red horses, and Desa.
According to the above statement, you can choose the number of Luohan fish to raise, but from a breeding perspective, raising Luohan fish alone is actually the best choice. There are many troubles when raising Luohan fish in a mixed culture, such as: Fighting between Luohan fish: The mixed culture of Luohan fish can easily lead to injuries or even sacrifices of some Luohan fish due to fighting.
Infectious disease transmission among Luohan fish: Keeping Luohan fish together will increase the spread of diseases. If one Luohan fish gets sick, it is likely to affect a whole tank of fish. In terms of parasites, if a Luohan fish produces parasites, the disease can be spread through physical contact or the feces excreted by other fish.
It is difficult to maintain the water quality of Luohan fish: Luohan fish is not as suitable for group breeding as small ornamental fish such as guppies. Luohan fish is relatively large and has relatively high requirements for water quality. It is easy to raise Luohan fish in a mixed manner. As a result, the water quality of the Luohan fish tank is difficult to maintain. The feces excreted by Luohan fish or the residues from daily feeding are the root causes of water pollution. Without powerful filtration, it is difficult to maintain water quality.
It is difficult for Luohan fish to come out of state: To raise Luohan fish in a fish tank, you first need a large fish tank. Usually we require a fish tank of 1.2m to raise a single adult fish. If you raise multiple Luohan fish in a mixed tank, For fish, a 1.2m fish tank is obviously not enough. When Luohan fish are kept together, problems such as space crowding, fighting, disease, and poor water quality are unavoidable. It is difficult to raise a tank of good fish. A tank of Luohan fish that is not in good condition will reduce its ornamental value and lose the value of raising Luohan fish. fun.
In short, it is more suitable to raise Luohan fish alone. If the space is limited, you can also raise two Luohan fish in one fish tank, but any more will undoubtedly increase the difficulty of raising them.
