I got one of these guys in May of '06 from the marinecenter.com . He's in my 20H along with a gramma, and he seems to be doing well. A few things about them:
-They are small. Mine is about an inch long, from about .75" when I got him.
-I have never seen him eat prepared foods. My guess is he eats pods in the tank. He's fat, so he must be getting enough to eat.
-I am not sure which prawn he pairs up with, but it doesn't appear to be the
tiger pistol shrimp.
-Relatively shy...he still skedaddles if he sees me coming.
Let us know if you pull the trigger!
