I wouldnt say they wouldnt eat any of them. I've never seen them do it, they usually have quite a bit of babies so I'm sure there may be a casualty or two. Best thing to do is just observe and make the best judgement. U will need to move them in time, so I would have at least a 10gal on the side with a sponge filter when u can move them. I'm sure u know but just dont add anything to the tank that may consider them a nice treat.
