Shark ID - Help wanted!

These are Bulls Sharks - click for detail!

Check this out!

What are those Sharks among those Grey Reefies?
Methinks Dusky/Galapagos (but possibly Bronzie?) and.... Pigeye (!!!) - the latter because she doesn't feel like a Bull, and because I read that from C. amboinensis, the bull shark differs in its lower, less erect first dorsal fin and higher, more erect second dorsal fin. The ratio of first:second dorsal height is 3:1 or less in C. leucas, but over 3:1 in C. amboinensis.

Opinions please!
