In nature JDs share waters with a number of Thorichthys species , Mayaheros uropthalmus and a few others.
With uropthalmus and other larger species they often suffer, because they are not as aggressive.
Note how torn up they are in the video below, where the uropthalmus dominate.

Yet in Cenotes where the JD is the only dominant cichlid, they do well

Many of the cichlids mentioned are "in my opinion" too large or too aggressive for a 110, especially one where you care about the JDs.
Grammodes ( I have kept many) too aggressive, and any Parachromis are some of those too large and too aggressive, buttikoferi would eventually have the JDs for a snack.
The only geographically correct cichlid I would consider that is readily available would be a shoal of fire mouths, or as suggested by Gourami Swami, maybe a couple from the genus Amatitlania (convict types) .
As to red tiger motaguense, I have found them much more hyperly aggressive them managuense.
I was growing out some 2" grammodes in a 75 gal, the largest killed 5 out of 7 within a month, I moved the 2 left to a 150 where they spawned 3 times, and then the male killed the female. They are shy retiring, hiding about 80% of time (except when guarding fry), but when on the prowl can be very deadly to anything that gets in view.
