No, Calypso never ate frozen mysis. She's the reason I have been struggling so to keep pods in my tank. My other horses grew to be 3-4 inches and she stayed at about 2 inches. I've worked with Pete to try to get her switched but she would never take anything but pods. She didn't show any signs of starvation but I suspect that's what happened. Now I don't have to worry so much about pods in my tank since the rest of my herd are good eaters. They get mysis enriched with special seahorse vitamins. Doesn't make it any easier though.
