Its best not too, parent raised is the best route to go. The young will never learn the parenting skills if removed from their parents. 2-3 weeks after free swimming is when you should remove them.
hey my pleco did the same thing! I have to get a 29 for the newlyweds. I have 6 angels in the tank. How dangerous is it to leave the other 4 in with the mating pair while I establish the mating bungalo? The large female is quite averse to my 2 dwarf--my wife's actually--gourami and I don't want any deaths in the tank.
