demjor19;1079180; said:if you are lucky 30". more like 20-24 in captivity. after about 16" they slow down very much in growth. it would probably take a florida gar close to a decade to even reach 24+ inches.
not necessarily a decade, but easily several years at least (in captivity). i have one now that is around 18" and i've had it for going on 3 years, with the fish being around 4 years old.
it's difficult to say, when there seem to be so few current records of captive gars kept in home aquaria for extended periods of time (i.e. over a decade). perhaps that will not be the case in the future, given that us current gar keepers are responsible and able to keep good info/records
