Feeding Fish in Your Fish Tank
Food is the source of your fishes nutrition, so using the right foods in the right quantities has a direct effect on the health of your fish
The food that enters the aquarium is the main source of waste and toxic pollutants such as ammonia and nitrites in the aquarium. If the quantity of food is increased then so does the level of pollutants. Overfeeding is the main cause of new tank syndrome and bad water quality in most aquariums. For this reason it is vital that the fish are not overfed, particularly in a new aquarium without a mature filter.
The correct amount of food to feed your fish varies with each aquarium so there is no set rule for feeding. In a new aquarium, the fish should only be fed once or twice a day and only as much as they will eat in a few minutes. If any food sinks to the bottom of the aquarium or is left on the surface after a few minutes then there is too much food going in the aquarium.
Once an aquarium is matured, normally after a few months, the frequency of feeding can be increased. Although one or two feeds a day is sufficient, feeding little but often is preferable for many fish. The times of feeding do not have to be regular, in the wild fish do not feed at a set time each day! Generally speaking, smaller fish require numerous small feeds whereas larger fish require larger feeds but less often. Some large cichlids such as Oscars only require feeding every other day when fully grown.
There are a number of different types of food available for aquarium fish and choosing between them can be a little tricky. A mix of foods is best for an overall diet and different foods have different nutritional values for fish.
