Cyprinidae species
Goldfish
One looks like a fantail. The other hard to tell from the pic possibly a koi. If there are barbs on the sides of the mouth koi. If no barbs probably a regular comet goldfish.
Welcome to the forum!
I agree these look like your classic comet goldfish - the ones you might see at a fair or sold as feeders. Still, they manage to grow up into one of the best looking goldfish breeds imo
