gars are not flexible like snakes. gar are actually quite ridgidsmijeha;4585574; said:alligator gars grow slow after the first 20-24 inches. ive read that they grow 20-24 inches in the first yr then about half an inch a year after that. i think a 2 foot wide tank is good enough for him right now and therefore not stunted. gars are flexible like snakes, so he can turn around fine in a 2 foot wide tank for the moment.
