The respiratory system is responsible for the movement of gases involved in cellular metabolism. Why is oxygen needed? Oxygen is needed because it is used up during the aerobic breakdown of glucose.
Also, rapid changes in the water temperature can cause problems for the organisms in the tank so the water should be kept at a steady temperature to keep the fish in a stable environment with plenty of oxygen. Lower temperatures are able to retain more oxygen. Our fish can live comfortably from degrees fahrenheit. Turbid water, water with a lot of particles of sediment or organic matter, can make it difficult for organisms to acquire or create energy because it can cloud out the light and, depending on the cause of turbidity, can cause problems with other water properties such as ammonia, nitrite, and nitrate. To avoid turbid water, the best solution is to clean your tank and change water often.
