This is very interesting, proving some centrals can hybridize with some SA cichlids. Convicts can spawn with green severum as well, though (I used to have some), so I'm not sure this is evidence you can generalize to show SA x CA hybrid potential, but is instead, great evidence of convict's strong genes. In other words I still think its not likley that CA & SA can cross with other "cichlasoma", but it is very likley that convicts can cross with other small south american species.
