Hi, I'm new to this forum, so....<wave>
This is an interesting wishlist. I'd say that the standard fish like guppies, swordtails, angelfish, and cardinal tetras probably need to be in there. But I would like to see some of the more unusual animals that go beyond the somewhat boring regular selections, something that people will see and go, Cool what's that?
My suggestions (sorry I don't know how to post pics yet, use Google):
Endler's Livebearers
Bumblebee Gobies
Ornate Bichir (which would eat the other two guys, but....)
Albino African Clawed Aquatic Frog
Ghost Shrimp
Marbled Hatchetfish
