no
Yes they can, I have a guppy (amongst other fish) with 4 goldfish together and they are very happily living together :)

some goldfish, mollies, and guppies
3:5Guppies:Total Fish
The goldfish should never be in the same tank as guppies. Goldfish are coldwater fish and need to be kept below 70F. Guppies are tropical fish and need to be kept above 70F.
Goldfishes and guppies should be kept in a different tank....
They should never be in the same tank because Guppies are tropical fish and like to be kept over 70F and Goldfish are coldwater fish and like to be kept below 70F. So Goldfish should not bite guppies because they should never be in the same tank together...
2-13
51-260
A total of four mollies can be found in the water tank
1 inch of fish per gallon so you about 18 but you will have the guppies eaten or the goldfish's fin bitten off as goldfish like to eat fish that are smaller than them (other than goldfish) and guppies are fin nippers so I would be careful or not keep them together good luck
Puffer fish are very aggressive fish and will tear the poor goldfish to pieces.
