'''Tropical fish''' include [[fish]] found in [[Tropics|tropical]] environments around the world, including both [[fresh water|freshwater]] and [[sea water|salt water]] species. [[Fishkeeping|Fishkeepers]] often use the term ''tropical fish'' to refer only those requiring fresh water, with saltwater tropical fish referred to as ''[[list of marine aquarium fish species|marine fish]]''.
Tropical fish are popular [[aquarium]] fish , due to their often bright coloration. In freshwater fish, this coloration typically derives from [[iridescence]], while salt water fish are generally [[pigment]]ed.
Tropical fish kept for home aquaria include the following:
* Wild-caught specimens.
* Single-species individuals born in [[Captivity (animal)|captivity]]. The latter category includes lines [[Selective breeding|selectively bred]] for special physical features, such as long fins, or particular colorations, such as [[albinism|albino]].
* [[Hybrid (biology)|Hybrids]] of more than one species.
[[recreational diving|Recreational]] [[Scuba diving|SCUBA divers]] are often enthusiasts of tropical fish as well. Some keep lists of fish species they have observed while diving, especially in tropical [[marine (ocean)|marine]] environments.
