Hey kaboom,
Just checked with 3 different suppliers and the only ones from your list that I can get right now are the Rainford's Butterflies, and they're on the not likely to survive in a tank list (along with the pelewensis), so not one we really want to bring in. Check out Bob Fenners article for more info

Not much available out of the Red Sea right now. I'll keep checking though.
