What's in a name?

So, yeah, I gave in and now own 3 bettas.  I saw this guy when I went in for some dechlorinator on Monday and ended up getting him on Tuesday.  I tried to resist, but friends and some folks online urged me to pick him up since truly black bettas are pretty uncommon and he's a delta tail to boot. Anyway, he needs a name.  My female betta is named Rosie since she's rose colored and the red male is Charlie since I like the movie The African Queen.  I can't think of a proper name for this guy, though.( Beeg betta pics behind the cut )
