[[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.
