Most aquarium fish fit into one of the categories below, but some don't. For the full list please see the alphabetical fish index, or search for fish by country of origin.
Cichlids? There are estimated to be over 2000 different Cichlid species in the wild, of all sizes, shapes and colours. Many require very specialist conditions such as those coming from the sandy/rocky waters of Lake Malawi and Lake Tanganyika. Others, such as the Apistogramma dwarf cichlids from the Amazon basin require softer water and a well-planted tank. In general cichlids do not make good community fish as they can get quite aggressive, especially when spawning - but a specialist cichlid tank is certainly a sight to behold, and can be very rewarding for the more experienced aquarist
