Tropical freshwater aquariums are the most popular choice for individuals new to the hobby. The maintenance and upkeep for a tropical aquarium is similar to that of a cold water (incredibly easy), but allows individuals to keep a lot larger variety of live stock.
Stock can include a large variation of fish, crabs, snails, frogs, lobsters and in some specifically designed aquariums, turtles too. The tropical fish available are typically more vibrant and radiant in colour than the coldwater selection. Community aquariums are the most favoured among enthusiasts as these thanks are a mixture of different types of community fish living within the same environment.
When purchasing a tropical aquarium it is important to be aware bigger is better. The larger the volume, the better the system will be, as it will be more stable. Fish waste and pollutants will be less concentrated as the larger volume will provide better dilution, in turn producing less fluctuation in water quality and a better system.
Larger aquariums also allow a larger number and variation of fish as certain fish are not suited to small aquariums. In summation when purchasing an aquarium always buy the biggest you feel comfortable with having, it results in an easier aquarium to keep that allows for more fish and a greater variation.
After the aquarium is set up it is critical that patience is spent introducing fish. You have to spend months stocking an aquarium to allow the bacteria to develop that biodegrades fish waste. This bacterium develops slowly to ensure the pollutants don't outbalance the bacteria only a couple of fish a week should be introduced.
Also when placing new fish in the aquarium they should be left floating within the bag for 10 minutes to acclimatise them to the temperature, then the bag should be opened and pegged to the side of the tank.
Now you should systematically add small volumes of your tank water to the bag over the period of an hour till you have 3 times the amount of water in the bag than you did to start with, this acclimatises the fish to the aquariums chemical conditions.
Now carefully net the fish out of the bag and place it in your aquarium. At this point turn your lights off not to stress the fish any more and leave it a good 6 hours before disturbing the tank. Take note that it is often necessary to pour some water out of the bag before starting this process as you remove the bag of water after and it can result in a lot of displacement.
