I have an RBTA that I got at the end of May from a split. It was three weeks old when I got it. Every 3 or 4 days I give it a little bitty piece of minced raw clam or shrimp. This week it split for the first time. They split to reproduce and will only split if they are happy with how you are caring for them. Don't try to move it, let it live where it wants in your tank, feed it a couple of times a week and just wait. That's it. But they like their tank parameters stable and reasonable water changes.
