I don't know if something like this would work for you, but one of the neatest 'community' combos I able to put together was a Delhezi Poly, JD, a school of 5 clown loaches , and a school of adult Congo Tetra. I also had a marbled sailfin pleco, and for a time raised a speckled bull headed catfish in the same group. It was a lively bunch.the Poly was chill. The JD brought the cichlid personality. When he matured - called a hollow log his home but still came out when I came near. The clown loaches frolicked pretty much the whole time. And the school of Congos was a constant splash of color swimming to and fro. I have to say though it took a long time , patients, and introducing each pet at the right time. This to greaten the chance for the survival of the Congo's, and to establish a preexisting community for the small JD. The JD did well with all except the Bullhead cat. They would fight over territory (hollow log). And the Poly left the Congos alone because they where already 3.5" and too crafty for his lazy butt to catch.
