According to Joseph Love's very recent and very thorough study on a Lake
Pontchartrain population (Southwestern Nat 49: 18-23):
males were 278 mm, females 299 mm at the end of the first year. Afterwards,
fish averaged 48 mm and 38 mm /year growth for the next four years, 16 mm
and 30 mm for the remaining years.
46 gal is not very big for a large fish with an "accelerator" type
morphology. Depending on the size of the gar when you get him (how warm you
keep him and how much food you give him) - a few months ?
