I have always wondered this as well, so I hope you do this, for now I am staying with GFC since I have multiple fish eating it. If I had CNBG only eating the food I would consider switching.

So I will be watching for updates.

I can almost feed 2 bags of GFC to 1 bag of AM 500, so I always wondered how that comparison would work out. I am sure if you feed the same amount of each food AM 500 will add more mass, but if you feed 1.5-2x the GFC to AM 500 would the results be different?

Thanks
