Feeding
Feed your fish the amount of food they can eat in 3-5 minutes. When you first purchase your fish, time it and take a mental note of the amount of food your fish consumed. If there is still still some food floating around in the aquarium, remove it with your aquarium net. Leftover food can cause the water to become very cloudy if not removed. Your fish can not be overfed, as commonly thought. They will only eat the amount of food their digestive system allows.
