Something I have always wondered and I have never had it answered even though I have had fish myself and I have observed when I have fed them to see if I can find an answer to my question but I have not been able to.
Do fish chew their food?
Depending on the kind of fish you have will depend on the kind of food you give them and whilst it will more than likely go soft in the water, I do wonder if maybe they have a way to chew it if they need to.
