It is strongly recommended that novice aquarists use the most common type of tropical freshwater aquarium. In this type of tank, various aquatic plants and species of fish can be looked after together, offering a colourful and lively display of activity in the aquarium. However, it is important to ensure that the fish not only get along in terms of their social behavioural traits, but that they also have the same requirements relating to water quality, temperature and aquarium set-up. However, this doesn’t mean that keeping the aquarium will become tedious. You can find a selection of fish from the various water layers in our example aquarium layouts.
