If you're a bird, I'm a bird
When they have absorbed their egg sac completely they will go from hanging to little swimmers, or this | to this __  Then you can feed them  
				
			
 
 
 
  I can see why they say that if you seriously want to spawn then you need a bare bottom tank
 
  I've only seen him munch one so I guess there must have been something not quite right with it.
 
  
  
  you have had a good day then you will loose some of the worms in the gravel, but they will hunt for the food anyway, but when you do a water change make sure you get the gravel as well as the dead worms will cause a problem if left to decay i always siphon into a clear container as you no doubt siphon a few fry so you can then see them after and put them back....... 
  
  
 
  and yes I expect some of the little fellas will enjoy a water chute ride  
  must mean they are getting enough to eat at least. They do mostly seem to have nice round bellies. I'm feeding Liquifry 1 twice a day and microworms twice a day too, but not too many.
