While I haven't kept cutteri in a large conspecific group, I've kept them with groups of other cryptoheros species, found them to be pretty typical for the genus. I think getting a group of 10 -12 young ones and growing them out (maybe in a smaller tank at first) would be fun and you would definitely end up with some pairs. You may have to re-home some to get a balance that works. I think goodeids of any sort would be a great dither. I kept ameca splendens in a similar setup, with a group of panamensis, and they did really well.
