So 5D05 and 5D06 would probably be the best to use in a normal pond setting correct, unless you are trying to feed some really small fish?

I was also looking at the 5D07 and it looks like it has about the same content as the GFC, so would it even be worth changing to something like that?

Actually what would the increase in % of protein need to increase to make it worth changing foods?

Like I said they seem to hit the GFC just fine, but if I can speed up the growth process and fine AM for a fraction more it would be worth it to me to switch.

Any ideas?
