ok, so i have an alligator gar (he's about 21")... i was thinking of getting him a tank mate. at the local fish store (non petsmart or petco) they have large piranha... like the size of your hand... too big to fit in his mouth. i was wondering if getting one would make a nice addition to the tank or would they try to rip each other apart?
also i was wondering if anyone else had any ideas of good tank mates...
thanks
my tank is 110g
