ok nothing stands out to me in the pics, as you said (but i wanted to see for myself to be sure)
that being said, i don't think there is anything wrong with your fish. if there was something seriously wrong physically it would show in some way via the pics. is he still eating? don't worry about any worms or white things on the eyes...if it were anchor worms this would also show up in a pic. i think you're seeing typical tank platyhelminths and other such organisms, all of which are generally harmless. just keep the gar eating well for another few days and you can likely move him after that.
how long has the new tank been set up? what is the filtration, size, and tankmates in the new tank?--
