Only if your serious about truely breeding them. If you just want them to maybe breed and maybe get a fry or so to live then go with your original plan of cardinals and bnp's. Your kind of in one of those situations where you have to decide which you want to have more. But even if you go with the community the cardinals and bnp's will like the IA leaves and the softer light. Another thing is if you want bnp's the albino's for some reason are more active during the day. I thought it was just mine until I did some research and found this is actually true.
