I couldn't be happier with my new BTA from liveaquaria. It's so much larger than I had expected. The site said 3-5" (med) but it's at least 8" diameter. My saddleback took to it within minutes. We stayed up late last night just staring at the tank. I also got a lobophytum (devil's hand) and a mangrove tuber for the fuge.

Had to share.
