so i decided to set up my 480G pond with shubunkin goldfish, I fell in love with a orange and black one at the pet store. Anyway i was wondering, I always wanted a florida gar in for 4,000g pond but I knew it would get to big and eat my GT and JD, so i got thinking and do think if a waiting for the goldfish to get 6 inches and added a 4-5 inch gar, if i could grow the Florida gar in there till he maxed out at 18 inch o so then switch him to the big pond?. The shubunkins get 12 inch and stay in the mid/bottom so im not to concerned about the gar attacking them. Is it possible?
