What julies did you have that stayed on the bottom? My dickfeldi were all over the place, and loved nothing more than to play hide and seek with other, larger fish. lol, they were a hoot to watch. They loved to get crap started, but never actually got into any fights.
Matt's right, brichardi aren't the most colorfull, but I loved them. I keep them in a 29 gallon as a species only tank for quite a while and just let them breed as they wanted. I didn't have to try to get them to do anything, they were more than happy to take care of everything on their own. The only thing I would think about though, is if you have REALLY soft water with a low pH, you might want to pass on the Rift cichlids unless your willing to spend a lot of time and dedication to buffering and monitoring the tank. When you artificially change the parameters things can go bad quick if your not very carefull.
