Juliechromis' are some of the best cichlids out there, they're too small to dig up plants, they can live in groups without a lot of problems, they breed very eaisily, and they can live in a small tank (one of my friends had four of them in a 20 gal with some other fish.).
Another thing about them is the fact that the fry are allowed to live with the parents for the rest of their lives! The juvinials assist the parents in the "maitinance" of the shells that they live in and also help defend their younger sibilings. The number of fish in the "village" effects when and how often the parents spawn, if you want to breed them remove the young as soon as they reach substantial size, other wise, just keep them in there, the parents like the help! The fry can be fed on micro-worms and powerd flake food as soon as they are free-swiming, they don't really need live food.
(Yeah, no need to hatch brine-shrimp!)
