Congrats! The first week I had mine, it wandered into the overflow strainer and 'accidentally' got split. Both have been doing fine! My girlfriend says she wishes I could do that so I could spend more time at home with her....
It's a very good RBTA as it is one of my splits . It's not unheard of to split into 3 but its not common. I've had them split into 3 once and even 4 on another occasion from a 22" monster. Congrats Mark!!!
