Welcome to Fishooo, your on-line guide for general tropical fish information, but specifically about freshwater tropical fish.

As the name suggests, freshwater tropical fish usually originate from warm countries in places like South America,

Africa and Asia, and live in fresh water, as distinct from salt water (fish that live in salt water are referred to as marine fish).

They are also used to living in warm water, so in most cases need to live in an aquarium with heating, as distinct from coldwater fish

(ie goldfish, koi carp), which do not need heating, and which can live in either an aquarium or an outside pond.
