yes, a fishes digestive system is very different from humans, in the wild the digestive system isnt always working since they arent always fed. In the home aquaria they almost always have food somewhere in there digestive track making it work 24/7. This isnt that good. Imagine lifting weights non stop.... Also if you keep feeding food there is a higher chance of them catching a paracite which isnt good. Not feeding lets there immune system come back to date and protect them. Ive heard people fasting there fish for 1 week per month. I think that is a bit far-fetched so once a week or once every 2 weeks.
