Is a guppy an amphibian

Answer 1

No. Amphibians are marked by a life cycle between a fish like state in which they are called Tadpoles and an adult state (often called frogs). When they hatch from an egg they are small tadpoles who mostly spend their time eating, growing, and avoiding predators. As the grow the develop legs, then loose their tail, they also loose their gills and develop lungs. At this point they then become adult frogs. Though there are other creatures that belong to the amphibian family (such as toads and salamanders) frogs are the most well known. Additionally not all frogs loose their gills and develop lungs (as some are aquatic and spend their whole lives underwater, but they still develop legs and loose their tail).

Goldfish on the other hand are part of a family of fish rather than amphibians. Amphibians likely evolved from some species of fish into a partially land dwelling animal. Fish however never develop lungs and remain aquatic (water living) animals their entire lives. They also don't undergo any similar changes. They keep their tails and never develop legs. Goldfish themselves belong to a subset of fish, and is closely related to carp, Koi fish, and other breeds of fancy goldfish such as Orando and Ryukin.
