gymnogeophagus

I've always wanted to try a Gymnogeophagus species. If I keep the tank on the floor by the door to the outside during the winter, I think I'll be able to get it into the mid-to-low 60's. At least that's what I'm guessing based on the temperature in that part of the room today. Is that low...

I was in the store recently and saw some Gymnogeophagus Rio Olimar and maybe Yerbalito. I was wondering if it is known whether they were imports from Uruguay (F0) or farm raised? Thanks.
