When raising luhan fish, the breeders all hope that they will start quickly, so that their ornamental value will be good. In addition to providing them with good water quality and adequate nutrition through feeding, they also need to give them some external stimulation, which can promote their rapid start. Can use the stimulation of water temperature, need to reduce the water temperature to 26 degrees first, when reducing, need to gradually reduce, reduce 1-2 degrees per day. Then, suddenly adjust the water temperature to 33 degrees, such stimulation can promote it to start.
The second way is to change the water stimulation, can carry out a large area of water change, such stimulation can also promote it to start. The third method is environmental stimulation, that is, to put the arhat fish suddenly into a new tank, so that the environment around it changes greatly. However, the water quality should not be too different, otherwise it will also damage the health of the Luo Han fish.
If you want the head of the Luo Han fish, in addition to paying attention to space, water quality, light and other factors, you also need a certain amount of stimulation. In addition to the water temperature stimulation, water change stimulation and environmental stimulation already described above, there are other methods, the effect is better. For example, feeding stimulation, generally speaking, needs to be fed every day, but they can be starved one day a week, so that they may have a head shot under the stimulation of hunger. There is also the stimulation of fighting, you can put a parrot fish about the same size as the Luo Han fish into the fish tank of the Luo Han fish, let them fight, such stimulation may also appear under the head shot.
