How big can RBTA get?

[goodtimes2]

I bought RBTA that was bout six inches across about 4 months ago, it split into two and one of them is at least 12 inches across when fully inflated, about the size of a dinner plate.The other is about 8 inches across. I am feeding it maybe once a week , what is the largest size RBTA that you have seen? If the tank is stable will it continue to grow or do they which a certain size and then split?

Right when I sold my BTA it was at least 15" across, and it had split shortly before that. Sure if I would have kept it it would have gotten even bigger.
