Fish Aficionado
The guy at the shop is stuck in 1975.
It is an old myth that fish will grow to the size of their tank, like your goldfish.
Whilst the outsides may stop growing, there is a very strong suggestion that their insides keep on growing and you can guess the rest.
Balloon Molly lifespans are the same as their non-Balloon relatives...3-5 years, in the right water conditions.
Your fish did not die of 'old age'...they'd died of poor conditions.
"...He accepted that my tank is overstocked...but not the worst one..."
But he still wouldn't help you out by taking some fish back.
He may have been a vet, but he is an ex-vet and is out to make money out of people like you.
Keep on with the water changes.
