Twins




 Hi All
 
  I'm kind of new to the hatching of annual fish eggs.
   So please tell me about 2 embryos in one egg?
   I had a bag of C hellneri eggs put up and not being sure about incubation 
times I sorted through the peat , found 4 eggs and put them under the 
microscope.  Much to my surprise each egg had two embryos in it, I never saw 
this before and curious about how often this happens. Judging from the number 
of fry I got they must have all lived. Hind sight is always 20-20 but I wish I 
had put 1 of those eggs in water then I could have observed the fry.
 Thank You for any comments,
  Gary
