Does brocollie make my fish fat?

Question

i have 3 shubunkin goldfish and i gave them a brocollie and leaved it there all day long. when i got back from outside, the green leafy parts were all gone. i was worried cuz i gave them a big one and they ate them all. there were some green poops on the bottom but will this make my goldfishes fat?

Answer 1

Fish can't get fat, if they overeat they die. You fish sound fine, its not like they ate 50 of them!

Answer 2

No, it's good for them.
