Sexual Dimorphism: The male is smaller and has a more accentuated coloration while the females are larger and with a large belly used for the gestation of their babies.
Habitat: Bentopelagic, freshwater and brackish water is not a migratory species and lives in tropical climates. He lives in running or steady waters. Temperature: 20-24 °C. pH: 7-8. Water Hardness: It suits well hard and very hard water.
Tips for Breeding: Guppy lives up to 5 years as evidenced by the life expectancy at AnAge‘s site. For aquarium breeding we recommend a medium-sized, well-planted tank with many hiding places. The appropriate number of individuals is a minimum of 5 specimens (3 females and 1 male), the number of females should always be higher than that of males because they are stressed with ease.
Feed: In nature it is fed with zooplankton, small insects and debris. In aquariums welcomes dry, freeze-dried, live and frozen foods.
Diffusion: Originally from South America, it is located in the areas of Venezuela, Guyana, northern Brazil and islands such as Barbados and Trinidad and Tobago
Swimming Level: Swim in flocks and prefer to swim in the middle area of the aquarium’s water column.
Difficulty: Very easy for neophytes.
Reproduction: Guppy reproduction is very easy and fast because they mate continuosly. After about forty days of gestation, the female ejectes the small, already self-defeating fry. Usually to save a larger number of fry, around the 38th – 39th day, the female is placed into a split partition room, thus separating the little ones from the mother by avoiding being eaten. For growing the small fishes, it is recommended to use a small container or transfer to a larger nursery. Fry up to 2 cm can be fed with dry feed in the powder by increasing, step by step, the granulometry or nauplii (larva) of Artemia salina. After 2 cm can be released into the aquarium.
Extinguishing Risk: Not at risk of extinction
