Can We Change the Type of Egg?

By 10:00 am this morning we were beginning to think we might not be able to find Minnow eggs by December 27th.  We made a call to SSEP to see if there was any possibility that we might be able to use a different type of egg for the fluids and compatibility test.  We were told that whatever we submitted for the fluids and compatibility test was what would have to fly on the shuttle.  Could trout be a possibility after all?  Were there any trout eggs smaller than 5 mm?  We asked SSEP whether it would be possible to change the type of egg in our experiment.  Minnow eggs were the right size but just really difficult to find.
