I personaly have 2 in a 50 gallon. But in all honestly they techniqly are pond fish and easily have the potential to grow a foot long if given the chance. But they are a pleasure to have. If properly cared for they can live up 10 years depending on curcomstances. If you do plan on getting one a good rule of thumb to follow if they will be living in a aquarium is 40 gallons for 1 feeder goldfish and an extra 10-20 gallons for every additional, so for 1 feeder you would need 40 gallons, for two 50 gallons.
Feeder/long bodied goldfish are aqtualy quite hardy and don't need a heater, but they do need a good filter as they are messy fish and produce a lot of ammonia.
Good luck with what ever you decide :)
