40 gal would be to small for gars and false gars. a needle fish would probably do well in a 40 but i dont have exp keeping them. but if you do invest in a bigger tank, id go with african pikes

Hujetas would not work in a 40. They are very flighty and sooner or later they will receive damage fromhitting the tanks sides.
Needle fish will not work because they are also lightning quick and are naturally a open water predator. My last needle grew to 14" before dying. 14" anything to big for a 40.
There are a few species of barracuda that could spen there life comfortably in a 40g.I can't think of there names right now, maybe minimus and isrealia which both max out at 4-5", But the chances of you finding them are very very slim.
My suggestion for a aggressive natural live eating predator for a 40g would be exodon tetra's or a single piranha like a red belly. With exodons you could get as many as your heart and maintenance schedule desires. 10 being the minimum number IMO. And 100 being max IMO.

What size tank should a needle nose be in I wouldn't keep him in the 40 for life just for now until I get more space
A 125 - 6" x 18" would work -they also make a 120 that's 4' x 2' x 2' that would give them more turning room as adults - Hujetas do better in groups of 3 or more. Check out the Stripped or Spotted Pike Characins too they have more color.
