OK, so I've gone and done it now...
I stopped by a new PetSmart that just opened on my way home from work...
I got 2 more clown loaches, and they had some really nice looking yo yo loaches... so I got 3 of them.
I also picked up 2 Japanese algae shrimp.
The clowns took a while to meet up, but now, 4 hours later they are swimming around together happy as can be.
The yo yos are happy and will school up w/ the clowns or just be off doing their own thing.
One of the shrimp didn't make it, my wife found it laying on the bottom of the tank, but the other one keeps popping up all over the place. He's really neat.
I added a cave for everyone, and re-arranged the plants and driftwood to make more hiding spots too.
I know I'll need a bigger tank eventually, maybe even w/ in a year!
