Not long after asking my wife about his fate, the DJ came on and said they were a gift to whoever had the nearest birthday. The other couple at our table won but were happy to let us have him anyway - lol! So, it worked out well. Fortunately, my wife knew a little bit about them from a roommate that had one in college. She assured me he was fine in his jar, and what an "easy to keep" fish they are - the usual routine they give unsuspecting animal lovers.
A couple of days later - and after some haggling - my wife begrudgingly took me over to the pet store to requisition him some of the necessary supplies. I was relieved to get him out of that jar. At the bottom was this annoying blinking light like the one from
Pink Floyd's Pulse cd, if you know the one I'm talking about. That thing is now sitting in pieces on my desk as I write this

I'm still shopping around for a bigger tank, but it's much bigger than what he was in and he's zipping around the thing like
Speed Racer.
I don't know what happened to the other fish and I probably don't want to know. They did hand out pamphlets about their basic care/needs. Hopefully, at least one person from every table took the time to at least glance over it. Everyone seemed pretty well behaved - more interested in making fools of themselves on the dance floor, or watching everyone else make fools of themselves on the dance floor.
Like my wife said though, "I bet no one else has gone to this much trouble over their bettas." Well, what can I say? I'm a sucker for critters in peril.
