I have raised a female festae with a Escondido, in a 360 gallon with other cichlid, all about 2" as they grew, the Escondido and Festae would battle, and the female festae would win and control the tank. I had a 5 spot Jewel in the tank that was relentless, I had to get rid of him. I latter added a black nasty and Beani. The Beani controled the tank, and I ended up loosing the Black nasty and Beani to stress. They all was around the same size. I almost forgot I also had two grammodes in the tank from with I still have. I ended up getting rid of the Festae, although I wish I hadn't done that. Any, I find that the Festae is not that aggressive when compared to Grammodes, Black nasty, Beanie, 5 spot Jewel, and Motaguense. At least the one that I had. The Festae held her own, but the others was more of a problem then the Festae as far a in a community tank. Just my experience. My two Escondido, are not that aggressive...
