Answer 1

Your Ruby Sharks (aka Rainbow Shark and Red Fin Shark) can not be reliably sexed. Some sites suggest that males have a slimmer body and / or that they have black rays in their anal fins, however this seems open to debate.

Breeding is extremely rare in captivity and seems to be based more on luck than on planning.

Here's a few links woth some information about them
