To be honest I only suggested EBJD because you seemed to be leaning towards that direction. I personally wouldn't get a JD for a single cichlid since they're... well, not that interesting. Pretty, but not interesting. Imo. I'd much prefer something like a green texas or some sort of Thorichthys like an aureum, meeki or ellioti. I personally have a T. ellioti in a tank with just a convict partner, and seeing it do all sorts of stuff - sift through the gravel, swim up top to eat food, jump out of the water (or yeah I forgot to mention elliotis like to jump), all that stuff is more interesting than yeah... a JD. But that's just me.
