Yes, that seems like a likely male. One or two males rise to the top of the pecking order. A dominant male will be lighter, nicer blue with longer pointed fins and more distinct eggspots. Female mbuna can have a weak eggspot or two but if fish are in a group for awhile, males will rise to be bosses and have more distinct eggspots.
You may have two males, or even more. It is just natural in a pecking order that you get one leader alpha, then a beta (2nd) to challenge the boss. If you have two males, they may fight alot for dominance which is why you want 1 male in a small group, the "dictator" always wants to chase away his closest competitor... but in a closed tank the challenger can't leave unless you take him out, so it can be constant war.
