If the goldfish is big enough and the guppies small enough, yes the guppies could well be eaten by the goldfish.
Also, guppies should never be with guppies are guppies are tropical fish and goldfish are coldwater fish.
it depends what your asking they eat duckweed and almost any real plant you put in and my gold fish dosn't seem to care about the plastic ons I put in it
They should never be together because Goldfish are coldwater fish and guppies are tropical fish.
