I'm not saying all fish are the same. I once was at a customers place where he exclusively fed Aquamax 500. The fish absolutely would NOT eat Aquamax 600. No way, No how. These were 2# HBG. They'd pick a single AM 500 pellet from the water that was floating right next to an AM 600 pellet.
When I switched from AM to Optimal (now Endurance) I mixed it 50/50 in the feeder for 80# then just went straight to Optimal.
Thanks for the info. I just bought 1000# of new food, yesterday was day 1 of switching. There was very little activity compared to the 5 days prior with the last of the old food, very well could have been the drastic weather change, today with the new food it was back to feeding like crazy. I got scared there for a day
