DIFFERENT TYPES OF AQUARIUM
An aquarium is not just a motley collection of plants and fish. Some aquarists
aim to reconstruct the biotope of a specific geographical region (Central America,
the Amazon, Asia, Africa), while others concentrate on a single group of fish (for
example, livebearers, Cichlids, or marine fish). Whatever the option, an aquarium
must be attractive and wellbalanced for its occupants to thrive, and this entails
some understanding of the various habitats, as well as their inhabitants.

An aquarium is a collection of elements - fish, plants, soil, rocks, water -
which are compatible with each other. However, there are several types of aquarium,
all sharing the same general principles and techniques but differing with respect
to the environment created. Aquariums are divided into two main groups:
- temperate aquariums, often mistakenly called cold water aquariums, where
the water temperature can range from 5 to 25°C;
- tropical aquariums, with either fresh or sea water. These cover the areas
lying roughly between the tropic of Cancer, to the north of the equator, and
the tropic of Capricorn, to the south, where the water temperature varies by
only a few degrees throughout the whole year.
