I agree to leave them all together. New parents usually have no clue what they're doing and you may have a couple spawns that they wind up eating them. It just happens. Set up looks good so far and helps give them a little "security feeling" the others won't be a threat.
On a side note, now that you've seen the female is capable of laying eggs on the vertical thermometer, I would highly suggest to turn the heater horizontal. IF she decides to lay eggs on that AND the element is on, it could sear the breeding tube closed. In time this will ultimately lead to a premature death as she will not be able to pass the eggs. Congrats and good luck !!
