Did I miss something? The OP never said anything about marbled. Marbled from what I understand is different genetics then pink. The offspring's genetics will depend on the genetics of the Black male (AA or Aa). If AA all the offspring will be black, if Aa then half the offspring will be black, half pink.This may be a very simple question to answer but oh well. I just separated a pair of my convicts into a 55 gallon tank... 3 inch pink female and 4 inch black male... how do I know what the likely hood of getting pink offspring is?
