Looking to Buy Fish for office tank

I need to add a bunch of fish to the Grove & Platt tank, right now it only had a medium Yellow Tang, a Tomato Clown, a Pajama Cardinal, and a goby. So I'm looking for friendly community fish but would consider most anything.

The last couple fish they bought and put in (without my knowledge) had either Ich or Velvet (probably both) and the entire tank was wiped out (that was a year ago). Went fallow for a few months then stocked it with fish from a tear-down and some of my fish, so far no wipeout-death reoccurrence.

So if anyone is tearing down a system and needs a new home for a bunch of fish, let me know. I'll probably QT them even though I've had really good luck in the past buying fish from established tanks.

Thanks in advance
Bud
