Although I haven't kept godmanni, I have kept Chuco intermedia, two different location variants, and micropthalmus, so my guess is they are similar in attitude. I have not found either to be overly aggressive, with any cichlids I kept them with in similar size tanKs. I did keep them with other cichlids that were dissimilar in looks.
I find keeping any cichlid with similar body style, and mouth shapes to be problematic because they often see each other as competitors. So if you do try to keep them with tuba, and nicaraguense you should have another tank , case things go south.

I have also kept both tuba and nicaraguense. Tuba were always aggressive with any similar shaped species, to the point of killing them.
