Would an alligator gar be okay in a 12x7x3ft deep pond that is 1750+ gallons? It would be intoduced as a juvi in the summer and be kept sdafe in a mesh livewell until 12 in and then set to roam in the pond. The pond will not freeze over because of the waterfall that is keeping movement. Not enough for a large amount of current, just to keep the water spinning. The water can get to about 30 or so in the winter, if slowly acclimated to the cold from summer to winter, could it live? I don't want to spend 80$ on a fish just to have it die after 4 or 5 months, actually more like 6 months. Thanks!
