Gambusia

GambusiaThe mosquitofish, Gambusia affinis (Baird & Girard, 1853), is a species of freshwater fish. It is a member of the family Poeciliidae of order Cyprinodontiformes.

These fish are native to the watershed of the Gulf of Mexico, where it has long been known that they feed readily on the aquatic larval and pupal stages of mosquitoes.

They are remarkably hardy, surviving in waters of very low oxygen saturations, high salinities (including twice that of seawater), and high temperatures; they can even survive in waters up to 42°C for short periods.

For these reasons, this species may now be the most widespread freshwater fish in the world, having been introduced as a biocontrol to tropical and temperate countries in both hemispheres, and then spreading further both naturally and through even further introductions.

Goldfish

Goldfish

The goldfish (Carassius auratus auratus) was one of the earliest fish to be domesticated, and is still one of the most commonly kept aquarium fish. A relatively small member of the carp family (which also includes the koi carp and the crucian carp), the goldfish is a domesticated version of a dark-gray/olive/brown carp native to east Asia (first domesticated in China) that was introduced to Europe in the late 17th century.

It may grow to a maximum length of 23 inches (59 cm) and a maximum weight of 6.6 pounds (3.0 kg), although this is rare; most individual goldfish grow to under half this size. In optimal conditions, goldfish may live more than 20 years (the world record is 49 years); however, most household goldfish generally only live six to eight years.

Guppies

Guppies

The guppy, also known as guppie (Poecilia reticulata) is one of the most popular freshwater aquarium fish species in the world. It is a small member of the Poecilidae family (females 3 centimetres long, males 2 centimetres long) and like all other members of the family, is live-bearing. It prefers a hard water aquarium and can withstand levels of salinity up to 150% sea water (58 ppt sodium chloride), which has led to them being occasional included in marine tropical community tanks, as well as more usually in freshwater tropical tanks. Its most famous characteristic is its propensity for breeding.

In its natural environment in South America and the Caribbean, guppies are often found as isolated breeding populations. In its native range, the guppy can be found in small streams and ponds of virtually any size. In Trinidad they are colloquially known as "millions" because of their fecundity.

In many countries with tropical, subtropical and mediterranea climates where guppies were not originally present, they have escaped from captivity and established naturally breeding ("feral") populations. It has also been introduced to some areas to keep down the mosquito population and help fight malaria, usually with mixed or negative results to the local ecosystem.
