Platy is still alive, though pretty scratched up. Is there anything I
can do for him or just leave him alone and see how he turns out?

You can isolate him and/or treat the tank with a mild anti-bacterial remedy
to speed the healing... something like Melafix or salt should be enough
unless the wounds are heavily infected. Isolating the fish may be tricky
if you don't have a quarantine tank as isolating it in the tank may just
stress it out further, but it is better than allowing it to attacked again.

If you don't find the culprit during the day time, try turning the lights
out a couple hours earlier than normal and watch for the attacker then.
