How much do I need to feed my goldfish?

[NewFishKeeper97]

I’ve introduced floating plants into my aquarium and my goldfish love to eat them. I know that won’t be enough to sustain them but how much and how many times a day should I feed them the flakes?

Twice. As much as they can eat in 30 seconds flat. Not 29 seconds, not 46 seconds... 30 seconds.
