Hey bloo, it's looking great, though I hope you don't mind some advise :D
You'll want some tall ornaments/or silk(or real) plants towards the top. that way you know the line of sight will be broken up and even the girl at the bottom of the pecking order will be able to surface for air. Because there can/will be a lot of nipping and chasing, the more ornaments and plants, the better.
Also, be sure to keep up with water changes, it seems to me you'll be doing a fish in cycle? If so, monitor the water params like a hawk XD.
also, tell the person to look for healthy active fish with clear eyes, no stress bars, responsive, etc. Believe me, treating sororities when they've all become sick really truly sucks.
