I bred panamensis in a 5' tank with a few extra panamensis and a larger hericthys tamasopoensis female. The panamensis staked out one half of the tank, and the Tamasopo took the other half (she would lay eggs solo).
They chased the other fish around, not any more or less than I would expect of breeding pair of convicts or their relatives. Eventually when I put them in a 4' 90g without other cichlids, the male killed the female.
I think in a 180, the panamensis would be fine with the vieja and probably also the robertsoni. Just keep an eye on them when they start breeding. May be smart to give the vieja a bit of a head-start in size, as they grow a bit slow.
