My aunt is convinced that Goldfish will only grow the size of the tank they are in. I am like "If that was true, then why would some people bother paying tons of money getting 55 gals if you could just use a 5 gal their whole life?" Besides, does she not ever wonder why her Goldfish only live a few months tops?
A Petco employee overheard me talking to my mom about this matter, and he butts in to say "well, they only live like a year anyway.". I should have told him not to put himself in other peoples conversations if he has no idea what he is talking about. But I just told him that they live more like 20 years and he just ignored me.
