Gambusia affinis
ft native of the southern United States, the spotted gambusia or mosquito fish
has been widely introduced to tropical and temperate areas of the world. It is met
in southern France, for instance, close to the Mediterranean coasts and even as
far north as Bordeaux! These deliberate importations were designed to reduce plagues
of mosquitoes, since the fry are voraciously fond of the aquatic larvae. In a sense,
then, it is not a "true" aquarium fish, but it is very sturdy and spawns prolifically.
You can raise it as live food for voracious predators like the Cichlids; or for
those fish with a tendency to refuse artificial foods, like certain marine species,
as it can survive a few minutes' immersion in salt water. Size: 5 cm.
