sorry to burst your bubble, but from what I've been told, Parrot fish, aka Blood Parrot Cichlids, are 99% infertile, unless you got Jellybean parrot fish, then you have a slim to none chance of breeding them. Although it's not unheard of that they MAY breed, it's just very unlikly. As for sexing, not 100% sure, Jellybean parrot sexing is easy, the females belly has more red to it than the males... Mabye this is the same way with Blood Parrots...
