I have a Male GT that is about 6"s and a Male JD that is about 8"s and tried them both in my 55g this weekend. Previously they had been in two different tanks.
I redisgned the tank with some tall plants across the middle to keep them out of each others faces.
After a couple of hours the two where fighting very violently with the JD being the stronger of the two. I couldn't hold off on them trying to get a pecking order, I figured it would be death so I had to put in a divider.
I think the only hope for these two to be in the same tank is a tank that is 6ft long, probably a 180 and have some other strong cichlids to dither. A 75g just wouldn't do it.
