Sorry for your loss, Deb.
Richer, I too have noticed that my clowns didn't like the larger sized PE, so I tried crushing. Didn't work quite as effectively as the smaller mysis (Hikari). However, PE mysis sometimes comes in a small size. The latest bag I've got, the mysids are no larger than the typical Hikari SW mysid. This smaller PE stuff is a total hit among all my fish. It's hard to guage mysid size through the bag but try sifting through the bags, there is a large size and a small size. The smaller stuff is worth the hassle of trying to find it IMO.
