I'd look Into a Salvini preferably a female for many reasons.
- amazing colors
- reasonably priced / readily available
- very hardy
- develop the same nasty temperament as many of the larger cichlids just in a smaller package
-interactive
I had a JD with a pair of cons and once the cons started breeding I got them a separate tank once the cometition for food was gone he got pretty lazy, but every fish is different if you like JD's as a solo pet go for it I'd recommend getting a small one that way it'll become responsive to you
EBJD's are very cool but man are they sensitive. I just lost mine, twice I have bought them as fry and cant seem to get them past 3 inches. I here this is common. Ever thought of puffers? I have two GSP's in my 75 they are very entertaining. Two would do well in a 50 gallon.
I'm a big fan of biotopes. Whatever you choose try and keep the same eco system. Just google some different rifts out of South America or Africa. Have fun with it!
