be oxygenated or not depends on the density of the fish tank. If the space of the fish tank is sufficient and the density of the fish tank is normal, there is no need for oxygen. Because they usually open the filter and replace the new water, the new water and the filtered oxygen are enough for them to use, so they do not need oxygen. However, when the feeding density is high or the container is small, the breeder needs to oxygenate them. Or they often raise their heads to breathe, which is also a manifestation of hypoxia. Breeders also need to oxygenate them.
Mickey fish need to be heated. Although they do not require high water temperature, breeders also need to ensure that the water temperature is within their tolerance range. Mickey fish like the water temperature is 22-26 degrees Celsius, if the water temperature is lower than 22 degrees Celsius, although they will not die, but there will be a loss of appetite and activity. If the water temperature is below 18 C, they will suffer frostbite or die. Therefore, it is better for breeders to install heating rods in autumn and winter to ensure that the water temperature is constant. Although they are tropical fish, the water temperature should not be too high, preferably not more than 30 degrees Celsius. In summer, when the temperature is high, breeders need to use fans or ice bags to cool them down.
