Never thought to try there. I can check tomorrow. I have one of them nearby but never go there.
I thought the PE Mysis was wonderful until somebody (either Matt or Lee) explained the difference.
Two things though. My fish eat suprisingly large or small pieces of food. I have a yellow clown goby (very tiny fish) that will eat PE Mysis without a problem. It is very fun to watch. I also have tangs that swim through the water with their mouth open grabbing tiny tiny specs of food in the water.
When you put stuff in the blender generally you turn it on and off quickly or use the pulse mode if it has one. Put the tougher or bigger stuff in first and then add the smaller ingredients. I use everything from fish filets to frozen cyclopeze.
