Is guppy a freshwater fish

freshwater The guppy (Poecilia reticulata), also known as millionfish and rainbow fish, is one of the world’s most widely distributed tropical fish and one of the most popular freshwater aquarium fish species. It is a member of the family Poeciliidae and, like almost all American members of the family, is live-bearing. (source)

Overall guppies are freshwater fish. Guppies are found in tropical habitats so they are also tropical fish. You can keep guppies in your freshwater aquarium. As guppies are tropical fish, you should try to emulate the tropical environment in your fish tank for guppies. Jun 25, 2021 (source)
While mostly found in freshwater, guppies can also tolerate brackish environments (a mix of freshwater and saltwater) and have colonized several estuaries (where a large river runs into the ocean). (source)

If you wish to keep guppies in saltwater, the aquarium salinity should be measured using a hydrometer between 1.003 and 1.010. If it’s a tank exclusive for guppies, you can opt for the lower spectrum. But since guppies are hardy fish, it won’t matter if the salinity level is slightly higher. Just slightly. (source)
Guppies are tropical fish that are used to warmer climates. This means that they should never be kept in water that’s lower than 60 F (16 C). That being said, guppies can survive if temperatures drop that low and are not meant to live in cold water. (source)
So without further ado, here is my answer to the above question: NO, guppy fish can’t live without oxygen. Guppies breathe by pumping water through their gills which takes out the oxygen from the water. Dec 13, 2021 (source)
So, can guppies live in a glass bowl? Should you keep guppy fish in a glass bowl? No, you should not keep guppies in a fish bowl. In fact, you should avoid keeping any type of fish in a glass bowl. Jan 8, 2022 (source)
What Water Is Best for Guppies? Like many livebearers, guppies enjoy pH levels at 7.0 or greater. They also like hard water with good amounts of calcium, magnesium, and other essential minerals. If you live off well water with high pH, you’re going to become one of the best guppy breeders ever. (source)
Guppies can survive in maximum water temperatures of up to 90 F (32 C) and a minimum water temperature of 74 F (23 C). The normal and survivable temperature of water for guppies is 74-82 F (23-28 C) to keep your guppy healthy and happy. Jan 30, 2022 (source)
Writing in The American Naturalist, scientists who conducted this experiment in Trinidad say they found that the guppies quickly adapted to the conditions in each river. Jun 30, 2009 (source)
Overall, our conclusion is that guppies and goldfish should not live together. It’s far better to choose to keep only one species or to house them in their ideal conditions within separate tanks. There many species of fish in the aquarium hobby that go perfectly together in the same tank setup. Nov 3, 2021 (source)
2 to 3 years Guppies live an average of 2 to 3 years. In the wild, guppies live an average of 2 years. However, in captivity guppies can live anywhere between 2-5 years. Although the average is typically 2-3 years in captivity, if properly cared for, guppies have been known to live up to 5 years. Feb 25, 2022 (source)
Since guppies give live birth instead of laying eggs, guppy fry (baby fish) are born more developed that most fish. Unlike egg layers, they start life as miniature adults. A guppy can start to reproduce at only 2 to 3 months of age. (source)
