I commented on a thread the other day about green terrors and tank size and was made out to be a 'fish nazi'.
Theyre called terrors for a reason and generally speaking, will need a large tank to tolerate tank mates.
A 4' 75 gallon is a good size for a single rivulatus or possibly a pair. They seem to tolerate non cichlid dithers better than other cichlids from experience, however I did have a 5 inch green terror that loved to pick apart the poor bristlenoses of various sizes.
