Although the first ones I tried seemed prone to bloat, .... by following a few simple recommendations and doing research, that was not the case later on.
As someone mentioned previously, they aren't a community fish. If they can't kill other fish in the tank, they may be intimidated into stress, and may bloat.
They are the only endemic cichlid to the island of Hispaniola so its not surprising that other "similar" appearing cichlids in the tank would trigger aggression.
As they are loaners in nature (except when spawning), they prefer a tank to just themselves, or as a compatible pair.
A pair i had lived about 5 years peacefully (most of the time) together in a 6 ft tank, until a week long winter power outage killed the female.

I did research on the water temps in their natural waters, and most places they were found, had water temps in the mid to upper 80s
They are omnivores, and some have found a diet too high in protein causes them to bloat, so I used a pellet high in Spirulina and algae as a staple.
I did not use salt, and more importantly IMO, always did enough water changes to keep nitrate below10ppm .

They are very attentive parents.

One of my favorite species of all time.
Ron Georgione had one that would constantly win awards at ACA (American Cichlid Assn) conventions.
Whenever a passer by would get close enough to its tank, it would accurately splash a shower of water on that person (me included)
They have an immense personality that can rival that of any cichlid
