That is very rude behavior Ryan. What..was he raised in a barn?
Mine did the same thing and I don't mind so much- reasons? 1) My water is too high in PH for hatching anyway 2) If they did hatch I would have to move them or watch the other fish eat the babies which is worse! 3) I have no desire to set up another tank and do more water changes 4) If I did raise them then I would have to be responsible and cull- which is even worse to me than watching the fish eat them 5) The survivors would need new homes. I would have to find buyers and ship them or watch them darken and die at the LFS....
Have you read your son the book If You Give a Mouse a Cookie? It is the same kind of idea. One thing leads to the next thing and it gets a little nutty!
So Ryan maybe you should buy the guy a beer to go with his caviar. The bottom line is they are showing you they in great health! Nice work my friend!
