as stated above, no "true" gar will live for any extended period of time in a 35g tank, so this group (Lepisosteidae) should not even be considered--

dude just set up a nice community tank. if you get any monster fish you will just end up mistreating them. a 35 gallon is far to small for pretty much anything. you could grow out some Datnoids but thats about it.
a pickerel would be cool. i was going to keep some of those before. i think i would even recomend a 75 for them though. if they get a foot you dont want to keep them in a foot wide tank.
