Well, OC, I was going to suggest you smuggle some across the border for me, but guess what I found? I unplugged my HOB filter tonight to give it a bit of a scrub, and I see this little flash of orange as I dumped the water into a bowl (thank goodness I didn't go straight to the sink!). It was my "missing" shrimp - I had figured maybe a frog munched it, but no, it was just hanging out in the filter! It's much smaller than the others, but otherwise looks great.
