mine is around 13 inch now, still waiting for proof of the elusive 2ft butti, find it hard to believe they get bigger than arapaimag can get one in his 56k gallon over a decade old! some tilapia look pretty similar to butti, maybe thats what you saw??? my tile in my tank on the side view are 600mm so judge for yourself on the size of mine, tank is 34 inch front to back!-)
