Do Guppies change gender?
No, guppies cannot change their gender. An easy way to tell male and female guppy live-bearers apart is to look at the anal fins. The males have a gonopodium which looks like a stick where the females have a fanned anal fin.
The male Guppy is one of the most popular tropical fish. They are bright and colourful which really stands out in any aquarium. Originating from South America, Guppies can be found in mountain streams as well as brackish rivers. Wild Guppies can be found around the world in places like Barbados, Trinidad, Singapore, Venezuela and the USA.
