I had a gar that was about 24 inches when I got it and not that fat around it was only eating goldfish. I got it off live food and in about seven months it was 33 inches and a least 6 inches across messing up all my fish in a 400 gallon tank that was 7 1/2 feet long 28 inches wide and 36 inches tall.Mine never slowed down at 30 inches long as some people have said,out grew my tank way faster than I thought and had to get rid off it,not an easy task not a lot of people willing to go threw the problems of keeping gator gars in large tanks with other tank mates.what I heard is true do not keep anything in with a gator that your not willing to lose.I can say I did and got it out of my system,now I am raising a spotted Florida gar and not having any problems with tank mates.You no what they say live and learn and i learned the hard way.
