In my 75 FOWLR tank I have a mated pair of Bangii Cardnals......Question: What is the value of such a pair? Is a mated pair a rare occurence? Is it worth setting up a breeder tank? Any links to the procedure for raising the babies? Upon cleaning my fuge I have found 4 baby Cardinals. How many babies do they normally have? Ect, ect. Your help is appreciated!!
