So long as the female doesn't get bullied too much then you should be fine (in theory there is no excuse for her not being pregnant with two eager males!!)  I agree though the best scale is 2-3 females per male, your female seems to be holding her own so if you don't plan getting more fish and don't want babies then all is okay  
				
			
	            
 excited for it is my first batch that I am trying to keep.  I currently have a 5 gallon tank that I put the fry in.  The tank only has a corner of gravel with a handful of plants.  I also have a heater in there, keeping the water just above room temperature.  I'm hoping that that is all I really need.  I currently have 15 or so fry darting around in there.  What do you suggest I feed them?  I've crushed up some flakes really finely, but I have not fed anythin to the fry yet.  I was told to also boil an egg, then take out the yolk and disolve the yolk in some aquarium water and feed it to them?  Sound right?? I really wanna keep this batch of fry! So any help/advice/suggestions would be greatly appreciated!! THANKS A BUNCH IN ADVANCE!
