I've learned that feeder goldfish contain no nutritional value what-so-ever. I work at PetsMart and have totally turned the aquatics department around because of all the information I have learned from this board over the past years. I turn people away from feeders because so many contain diseases and it's not worth the chance of passing diseases onto our fish. I've also heard that feeders are almost completely fat, and contain no protein or vitamins/minerals that our fish need in their diet. The problem is, my manager over heard me telling this to a customer, and wrote our district manager, who in turn replied saying that I am totally wrong. He told my manager that feeder goldfish are imperative to a fish's diet because they are a great source of protein and calcium. I know this isn't true, but I need evidence to show my manager. I got a note put into my file saying I keep telling customers wrong information. My manager is extremely nice, and is willing to remove this from my file and leave me a better review if I can provide evidence that goldfish don't have nutritional value. Can anyone please help me by providing some sort of a goldfish's breakdown of nutritional value? Or some sort of a link to a website giving the facts? What is everyone's opinion on this issue? Thank you so much! ~Bryson
