What do you keep your tank temp at and what/how often are you feeding? Seems like you should be seeing more pair action by now.
Tank is about 79, on workdays I feed once when I get home and a few hours later I'll toss in a treat. I feed New Life Spectrum cichlid formula, and frozen bloodworms. I also put in a chunk of zucchini for the pleco, but everyone eats off of it. I'm sure they probably are paired, I just haven't been able to sit and watch as often as I would like to really see because I have a 1 year old, a 2.5 year old, a 4 year old and a 5 year old child, and I work M-F.
I actually need to see who's paired and probably start moving some around. They're currently all in a 29 gallon together. (same footprint as a 20 long) I want to set up a 40 Long or a 55 for them so I can keep two pairs at least.
