Tropical fish have high requirements for water temperature. The water temperature should be controlled at 25 degrees Celsius. Too low water temperature will affect the activity and feeding situation of tropical fish. If feeding and swimming are hindered, tropical fish may die slowly.

The owner should help the tropical fish to change the water 2 to 3 times a week to ensure the water quality is clean. Just replace one-third of the water. When changing the water, the temperature should not change by more than 1 degree. It is enough to feed general feed and nematodes. It is fed once a day in the morning and evening, and the amount of feeding should be eaten within five minutes.
