I actually love the idea of having a small colorful school of fish in the tank. Plus, I would still be staying on the Freshwater sides of thing, so it wouldn't be that much of a change.
Now I just got to check if they are all compatible with each other. :P
In a few weeks, or month time when I move to my new house, these fishes should be on top of my list, well after un-packing.
Thanks SO Much for the great ideas, "amq" and "neilanh".
