Freshwater Aquarium Fish - Adding The Fish
15. Adding the Fish It is very important to make sure that everything right from pH balance to the growth of beneficial bacteria is suitable enough for the fish to survive before you put them in the aquarium. Initially, introduce comparatively tougher species of fish in the tank. The excreta produced by the fishes would help in multiplication of beneficial bacteria in the aquarium. Acclimatize the fish before putting them in the aquarium water. Directly placing them straight from the bag into the water may shock the aquatic animals and leave them susceptible to diseases. It is good to place the closed bag into the aquarium for about 15 minutes before the temperature equalizes. Add a cupful of aquarium water to the bag and after a few minutes gently let the small bunch move into the aquarium. Monitor the ammonia and nitrite content of water for a few days. It is natural that the nitrite level would rise but make sure it also comes under control within a short time span. This will ensure healthy levels of bacterial growth in the water. When the levels remain satisfactory and stable you can add another bunch of colorful fish to your aquarium. Remember not to overcrowd the aquarium more than its capacity. A freshwater aquarium can accommodate fish according to its size. Multiply the length and breadth of the aquarium in inches and divide it by 12. The resultant number would tell you how many fish you can maintain in the aquarium. A small quantity of food once a day, is enough to keep the fish going. Do not feed your fish excessively as it may increase the waste product concentration in the aquarium to unmanageable limits. It can harm the fish. If you still face a problem with the water inside, you can replace 20% to 30% and add fresh water to it. Do not go beyond this percentage as it can prove fatal for the fish.
