You will want 1 male or 3...especially on the zebras. I would add 2 female saulosi and 4 estherae (red zebras) for every male in that species group.

I like 1m:7f Pseudotropheus cyaneorhabdos Maingano for a brilliant blue.

Not anymore than estherae IMO. With the right tank dimensions and the right ratios and the right tank mates...most fish are fine and not tank killers.

I did have them in the demasoni tank for many years and may get them again.
