Do Guppies change gender?
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.

This is misinformation and should be deleted. When females outnumber males they most certainly do change

Hate to disagree but I’m looking at male guppy that WAS female last month. It bore at leat one clutch of fry. I was reduced to a tank of only females then I noticed one with a gravid spot whose anal fin appeared to be narrowing. Now the gravid spot has disappeared and the anal fin is a functioning male organ, whatever its called for a guppy
