Day1:
When I took my first look at the eggs I wasn't sure what to expect. What I saw was breathtaking. Within the confines of the egg were a number of small orbs. Initially I thought that these might be individual cells that had developed in the ~12 hours since the eggs were fertilized. A friend of mine who looked at the images however suggested a much more plausible explanation that they were probably lipid/carbohydrate deposits in the yolk. As it turned out, I believe this is the correct explanation as the cells of the fry are MUCH smaller than this (as you will see later).
 
Day1 - Yolk: The yolk sack shows many spheres which are likely related to energy storage for the growing animal.

After looking at a number of eggs I noticed one other important thing, the eggs were polarized (i.e. they had a direction). In almost all cases there was a 'top' to the egg in which there was a space between the yolk sack and the egg cortex. At this time I could not see any noticeable structures or movement in this area (or the egg as a whole) As you will see however, it is in this area, between the yolk and the cortex where all the 'magic' happens.

Day 1 - Yolk: An obvious gap is present between the yolk and the egg cortex.
