Answer:

15 more goldfish.

Explanation:

Since there are 6 times as many goldfish as guppies, then.

#• 1" guppy"to6" goldfish"#

#• 2 " guppies"to12 " goldfish"#

#• 3" guppies"to18" goldfish"#

Now 3 + 18 = 21 the total fish in the tank.

Hence there are 3 guppies and 18 goldfish.

and 18 - 3 = 15, thus there are 15 more goldfish than guppies.
