The guppy (scientifically known as Poecilla Reticulata and anecdotally known as the 'million fish' and the 'rainbow fish') is one of the world's most widely owned and traded tropical fish species. It is arguably the most popular freshwater aquarium fish species. Guppies originate from the freshwater streams and rivers of South America but have been introduced to many different habitats across the world. They are highly adaptable and hardy fish and can thrive in many different environmental and ecological conditions. Interestingly guppies have 23 pairs of chromosomes, which include one pair of sex chromosomes, which is the same number as humans. Due to their popularity there are many different color morphs of guppy. Selectively bred guppies are normally characterized by having larger bodies and more intricate patterning (such as the snakeskin or grass guppies). Before purchasing any fish it is important to understand that as a fish owner you are responsible for the care and wellbeing of your fish. It is important to try and learn as much as you can about the fish you are considering to keep. You need to make sure that your lifestyle, household and financial status are suited to provide your fish with the best possible care. This guide has been designed to provide you with both precise and concise information about a guppy's basic needs to help you provide your fish with the best quality care and aquarium practices. This guide also goes into the benefits of cycling, having a decent filtration system, plants and how to plant them. This book was previously published by 'FIsh Care Manuals' under the same name.
