Started with 6, 3 have died, water is fine, and they all are losing their beautiful coloring, any ideas?

gbr's can be very hard to keep healthy i have found. And to keep colour even harder. You have to make sure what sex you have and what else is in your tank? Are there plenty of hiding places. Good oxygenation? And what are they eating? Any indication of how the first three died, i.e. fighting.
