I agree with Grum, when you place any Andinoacara with other more aggressive cichlids, they will not look their best. In fact..
using other species of cichlids as tank mates in cichlid communities is also not a great idea, it is best to use non-cichlids for tank mates if you want your preferred cichlid to look great.
In nature GTs don't come from habitats with other species of cichlids around, they are the dominant territorial form.
As an example
Its the same for JDs.
When they are the dominant cichlid in their habitat, they thrive, but when they have to share, they tend to get edged out, or suffer.
Below two videos that show this.
First a video in a large Cenote where JDs dominate.
Note the fish they share habitat with, Sail Fin Mollies (P. velifora), and Rhamdia catfish.
Now below, a much smaller Cenote (only maybe 5 to 10 thousand gallons) and they are few and far between and quite torn up.
I consider one of the worst pieces of advice aquarists are given, is to use other similar cichlids as tank mates.
Combining similar shaped blue spangled cichlids together such as GTs, JDs, or the Texas clade is contrary to nature.
All are so similar its obvious they are competitors, and are not/would not be found together in nature.
And unless your tank is several hundred galloons, its just not big enough to territorially divide up.
It you want a cichlid community that works, combining very different shaped and looking cichlids is best.
An example
The above cichlids are found together in nature, and look different enough from each other, to "not" be competitors, and live in habitats where many cichlid species are found tother.
Many Central American types, live in single species dominated habitats, i.e. M beanii, A islanus, N haitiensus, and/or are the only species of their genus in a habitat, most Parachromis, and Herichthys.
