Clownfish fry hatching at different times

[swill]

There were only 20-30 eggs to begin with. 1 hatched last night before I went to bed at 11pm and when I woke this morning all the eggs were gone. The 1 that hatched didn't make it through the night in the fry tank oh well...hopefully they will have more in the next batch. The odds are against me when only a total of 4 hatch and are caught before being eaten.
