Guppies have many predators, such as larger fish and birds, in their native range. Some of their common predators in the wild are Crenicichla alta, Anablepsoides hartii, and Aequidens pulcher. [35] Guppies' small bodies and the bright coloration of males make them easy prey, and like many fish, they often school together to avoid predation.
P. picta is distributed throughout northeastern South America, including Guyana, Suriname, and Venezuela, and the Caribbean islands, a range it shares with the closely related guppies P. reticulata and P. parae. [2] [5] P. picta occurs in lowland habitats such as slowly-flowing waters at stream mouths and still water lagoons. These are often ...
The original japan blue wild type guppy was a Poecilia reticulata collected from Lac du Rorata. Lac du Rorota is a reservoir in French Guiana. Karen Koomans received a single male japan blue guppy and crossed it with Cumana Endler females to preserve the strain. Karen Koomans introduced this strain to the hobby as the 'Japan blue wild type guppy'.
Many color and tail pattern varieties exist. They generally need a ratio of 1 male to 2 females or more. All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks. [58] can live in full sea water [59] 66 °F - 84 °F (19 °C - 29 °C)
The WWF divides the Earth's land surface into ecoregions, defined as "large area[s] of land or water containing a distinct assemblage of natural communities and species". Ecoregions are grouped into complexes and bioregions, defined as, "a complex of ecoregions that share a similar biogeographic history, and thus often have strong affinities at ...
Freshwater environmental quality parameters are those chemical, physical and biological parameters that can be used to characterise a freshwater body. Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations.
The “wild swimming” trend — aka open-water swimming, or taking dips in lakes, rivers, streams or even the sea — isn't exactly new. Still, it has been increasing in popularity over the past ...
At the source the Gillbach provides cooling water for the Niederaussem Power Station. As a consequence, the stream is much warmer than most other streams in Central Europe and even hosts tropical fish species like guppies [ 2 ] or convict cichlids [ 3 ] that have been released by private pet holders.
