Bah, I've got a massive turbo in my tank that takes things out. I'm just waiting to find this thing stuck to an favia or busted up but so far this is one of the faster growers in my tank. For the most part I think the larger the piece the more color variation you get, I'd be trying to get them to grow together for that reason.
When it comes down to it no one can tell ya what to do
You bought it, sell if you want.
