i currently have a 20 with some guppies, mollies, a barb, goldfish, and glassfish. i am going to get a 20g long and im not sure what 2 do with it. i want to add some turquoise rainbows but i dont know what else. im thinking of putting the guppies (4) in there and mayb getting a small school of tetras in there to but im not sure. any suggestions

the tank has a heater and the goldfish is a feeder fish but i loved him so i kept him instead of giving him to my turtles
