well, goldfish don't need a heater, so if they can live with a goldfish, then yes, they shouldn't need a heater. I'm gonna try to put a couple mollies (maybe like 2, or 3) in with a goldfish. they "would" be in a, um, I think it's a 1 gallon tank, that has an air bubble filter, thing, that goes in at the bottom of the tank, and it also has a hood, with a light.... You should try it, cause you never know what nature will bring you! Have fun! :):):)
