I still have mine, going on about three years now is my guess. Love it, super healthy and beautiful. It has cloned on me only once (I know exactly what caused it to split too) but the clone was really puny and didn't make it. When we saw that it wasn't doing very well, we tried moving it over to the big tank to see if it liked it there better, but it just disappeared.

I also have a RBTA in the big tank that is similar in color that I got from ErikH. I've always wondered if that originally came from yours.
