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.
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'.
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.
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)
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.
Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations. They include the natural and man-made chemical , biological and microbiological characteristics of rivers , lakes and ground-waters , the ways they are measured and the ways that they ...
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 ...
In the wild, they eat zooplankton, and will not accept anything else in the aquarium. They also need to be fed nearly constantly, three times a day at least. The best way to ensure the health and longevity of an Anthias is to attach a refugium where copepods can be grown to "drip" into the display tank. Unlike many other saltwater aquarium ...
