which could help us out of our predicament.

Guppies are not a good idea -- with their largish, colorful tails, they
look too much to the betta like another betta, and he'll attack them
(from what I understand). With such a small aquarium, you will be
rather limited on how many other fish to put in it, or else you would
need to do water changes more often.

At least one fish comes to mind right away, but it's a schooling fish
and there's not enough room in your setup for half a dozen of them.
Anyway, I'm interested in the outcome of this thread as well, since I
want to get a betta. I saw a beatiful little red and blue fella last
night, but I was good and didn't get him since I didn't have anything
set up for him yet. I was considering an Eclipse Three system, but I
found out that the current is too fast for most of them. Back to the
drawing board.
