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.
The most commonly kept species are guppies (P. reticulata), mollies (P. sphenops or P. latipinna), and Endler's livebearers . Members of the genus readily hybridize with each other and so most commercially offered fish are hybrids (with guppies having some Endler, and mollies being a mix of common and sailfin mollies).
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.
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.
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 ...
The guppies temperature and water quality is taken in a book "aquarium for Dummies", it would be good to have science papers about that, since every book and internet site, even the most popular and trusted, all gives different temperatures, etc...
