If you read up on the F&W cichla introductions to South Florida, Temensis were initially in the mix. It was Tems, Occell, and Mono. Tems were the ones that didnt cope with our colder temps. That doesnt mean that they couldnt have interbred. I wouldnt completely dismiss Tem genes in these guys, however after all the generations, Mono/Occel are what you will find.
