Size/age (yoy , fingerling and adult) are a big factor also. Yoy/fingerling BG and LMB (most fish) have a much higher growth rate in their first year so they can use the extra protein. Adult BG not so much. But it also depends on the extent to which your feeding is supplemental. If you have high densities of fish depending on feed (aquaculture) then higher is better. On the other hand if your fish are by in large eating natural food with the pellets as a small supplement then higher protein is not as needed.

Depending on the circumstances I mix GFC and Aquamax. In doing so the fish oil from the Aquamax gets on and adds to the GFC. I use/add the size Aquamax most needed to the smaller fish being fed and the application (often 50% protein fingerling food - sinking , or AM 400 with 45 % - floating).
