so I decided i want ot get a gar,specifically a spotted one because its the smallest.what are the dimensions of a pond that i would need for him.and maybe a channel catfish or some bullheads as tankmates. another question is how if i get a bunch of small fishes from where he lives and put them in the pond, would that work as a feeding method for him along with pellets, or would they ignore the food i give them and only eat the fishes.
