Odd snail/ Sargassum Shrimp?

[Marc G-L]

Any clue which variety if snail this is? Found it attached to Sargassum on Delray Beach, Fl. Also collected 4 varieties of Shrimp. One chocolate brown w/ white blotchrs and small pincher claws on front legs 1-1.5 inches in length [ including rostrum], another variety light amber with iridescent blotches.

Are these critters reef safe?

Pics of the snails under white light would be useful here (even the whitest settings on most reef fixtures are super blue heavy), but the first and third snails are probably safe; the second snail is a crown conch (not a true conch; not reef-safe).

The first shrimp is a Leander species (I haven't looked into these in depth yet or I might be able to give a specific species ID) - most likely reef-safe. I can't see the second shrimp well enough to attempt an ID on it.

Slightly better shot of shrimp. Not sure if it's an Leander species. Definitely elusive.

Bah, I forgot I had looked into these before (a recent thread reminded me):

+1 to this - Female Leander tenuicornis (differentiated from males by the ocelli - the spots on the side there - and by a taller and wider rostrum; not all females have the ocelli, but males reportedly never have them; male rostrums are shorter and leaner):
