Sometimes you don't, at least not right away. Many if too small must mature some before they can be ID'd properly. Others you may just end up with a genus designation without ever knowing the species.
2) How can I tell when a coral frag is alive or dead?
Knowing the natural behavior of a given species helps but barring that, the general look of the coral is really all you have to go by. If a zooxaanthellaete, does it extend during daylight hours, any signs of white fungus, excess mucus, necrotic black tissue, bleaching, color uniformity, self propogation and so on. The list is pretty endless.
Posting a pic would help.
