Are fish classified as reptiles?

No. Fish are one of the five families of vertebrates (animals with backbones) that include fish, reptiles, amphibians, birds and mammals. Fish are similar to reptiles being cold blooded, they lay eggs, and have scales, but are different from reptiles as fish breathe through gills and live exclusively underwater, whereas reptiles breathe through lungs on land. Fish lay eggs that have thin membranes (skins) in water. Reptiles usually lay eggs with thick leathery skins on land.------------------------------------------------------------------------------------------BUT,fish pretty much evoled to make reptiles.so if you look at it,reptiles are like land living fish!both have scales and most lay eggs... a FISH is definitely NOT A REPTILE.... fish are in the family of fishes. and although they seem like a reptile with teeth, scales and dinosaur-like, they are completely different from reptiles like their insides, fins and skills. hope my answer helped! :)
