Quick update (in case anyone's interested

)
So on Wednesday I was able to buy some NLS "Finicky Fish", hoping that with a name like that, there would be hope for my CBB taking it. I soaked it in with some mysis for an hour or so, then offered it to the tank.
Unfortunately I was not able to successfully seperate the mysis from the pellets afterwards, so there was still a mix. The CBB shunned the pellets and picked out all the mysis bits. Won't chase down the pellets, only the mysis.
So on Thursday I found some clam juice at Co-op. There is was, a jar of opaque liquid literally called "Clam Juice." (On the back it says - "Ingredients: Clam juice.") So I tried soaking some pellets in this stuff for a few hours and tried offering those to the tank.
May I just say, by the way, clam juice reeks. Took a sniff of it and ... yup. This smells like clams. Quite putridly strongly I might add.
Mr. Finicky STILL shunned the pellets, although the stinky pellets were a hit with everyone else (tang, hawkfish, 6line, angel) who all went berserk chasing after them. So I'm hoping a few more tries of this and he'll observe the others and maybe make the mental connection that it might be OK to try eating.
