John, Sorry you are having this problem as I found that McMasteri to be excellent parents. Capable of rearing three broods in the tank at the same time without problems from either male or female, perhaps I have been lucky. I read with great interest your posting and it is the last sentence that bothers me >They have eight baby cardinals for dithers< Oh dear, I'd get those out of the tank even although you say they are babies! No doubt others on the list will advice you differently.
