Colorful angelfish is a tropical fish, which is suitable for growing in a warm environment and requires a higher water temperature environment. Under normal circumstances, the most suitable temperature for its growth is between 25-30 ℃, when the temperature exceeds 30 ℃, it is a high temperature environment, when the temperature is lower than 25 ℃, it is a low temperature environment, these two temperature environments will affect its normal growth state, easily lead to its reduced immunity, susceptible to various diseases.
Under the condition of artificial feeding, the fish can be maintained at the water temperature of 30 deg C at the initial stage of feeding until it becomes an adult fish, and the water temperature can be reduced to 28 deg C at the stage of breeding the seed fish, which is more beneficial to the development of the gonad of the fish.
Colorful angelfish has very high requirements for water temperature, so it is necessary to ensure that the water temperature is within a constant range during maintenance. When the water temperature difference exceeds ± 2 ℃, it is easy to catch a cold. If the water temperature fluctuates greatly for a long time, it will easily lead to the reduction of its immunity and susceptibility to various diseases.
When the water temperature is between 24-26 ℃, it belongs to the low temperature environment. At this time, its growth and development will become slow, and its life will be threatened in serious cases. In order to facilitate its growth, when the water temperature is too low, a heating rod can be used to heat it up, and the water temperature can be adjusted between 28-30 ℃.
