SMB, the largest I seen around here was 2ft this guy traded it in cause it was getting to big for his tank, the poor thing was all banged up, I took him from the LFS to care for. an put him in a 125 by him self. had to treat the water MALACHITE GREEN, an a ton of water changes just to get him healthy, an fat. after that he got a new home 400+gl tank, more of a pool w/ rocks around it inside in private retierment home. I had them order a 1ft bala when it came it was huge.
I went there 2 week ago to see how thing were going an they were happy, happy, happy.
