Guppies prefer a hard-water aquarium with a temperature between 25.5 and 27.8 °C (78 and 82 °F) and salt levels equivalent to one tablespoon per 19 L (5 US gal). [60] They can withstand levels of salinity up to 150% that of normal seawater , [ 61 ] which has led to them being occasionally included in marine tropical community tanks, as well ...
In a home setting, these fish need well-oxygenated water with a pH level of 6.8 – 7.2, optimal temperatures varying between 72 and 82 °F (22–28 °C), and plenty of aquatic plants to give them hiding places amid their school. If properly cared for, Rainbowfish can live up to 5 years in captivity. [5]
Among aquarium fish, livebearers are nearly all members of the family Poeciliidae and include: guppies, mollies, platies and swordtails. [ 1 ] The advantages of livebearing to the aquarist are that the newborn juvenile fish are larger than newly-hatched fry, have a lower chance of mortality and are easier to care for.

Guppies are a common example of feeder fish. Feeder fish is the common name for certain types of small, inexpensive fish commonly fed as live food to other captive animals such as predatory fishes (e.g. aquarium sharks, farmed salmon and tuna) or carnivorous aquarium fish (e.g. oscars, gar, grouper and rays), turtles, crocodilians and other piscivores that naturally hunt in fresh, brackish or ...
The ideal temperature for sleep is typically between 60°F and 67°F for most adults, says Martina Vendrame, M.D., neurologist and sleep medicine specialist at Lehigh Valley Health Network.
A thermal optimum is either a portion of a specified geological time span in which the average temperature was above that of the average temperature for the entire specified time or the optimum range within which a biological process may take place or the ambient optimal range for a species' niche.
P. picta forms a clade with P. parae that is a sister taxon to the common guppy, P. reticulata. [2] Some authorities place the species in the genus Poecilia, subgenus Lebistes, along with P. reticulata, P. parae, P. branneri, and P. amazonica; others place it in the genus Micropoecilia along with P. parae and P. branneri.
