The water temperature of the Rockwell angle hanging is best at 21~27 degrees Celsius. It is best not to change the water temperature of the Rockwell angle hanging suddenly. If the water temperature suddenly exceeds the original temperature by 7~8 degrees, the Rockwell angle hanging will not adapt to it. Severe cases will lead to death, and young Rockwell's horns are more sensitive to changes in water temperature, so people who raise Rockwell's horns should be very careful about this issue.

In addition, we should also understand the diet of Rockwell horn hanging. The horns mainly feed on planktonic algae, aquatic insects, water worms, and freshwater shell vegetables.
