Somehow I've missed this tank up until this point. I just read all 14 pages and now you owe me a cup of coffee because mine got cold while reading!
Really great tank, well thought out, well built, and the result is beautiful. I didn't see it mentioned earlier but I could have missed it... did you do anything to secure the rock structure together? I'd be worried about one of the volcano rocks falling and hitting the glass!
Great build. When I die, I want to come back as a fish and live in your tank.
THANKS!
The Volcano itself is comprised of 5 large rocks. The right side is one complete rock from top to bottom. As such, it stay put very well. The front piece is one piece as well and the smiling Acropora God (pictured in someone's reply!) helped by making the right piece and front piece interlock in such a way. Very solid, and both use the center overflow as the main "foundation." The left side has one piece that is supported by a 2" T joint PVC underneath and is resting against the center overflow and will be held in by placement of the T underneath. Then, the "shelf" piece or "basin" piece extends out but also covers 100% of the overflow. So, the middle part of it is on the overflow ledge and supported by the drain (which I have used the elbow with a hole in the top method to regulate overflow sound). That piece is rock solid. Lastly, and the only fragile part is the the Volcano Tip itself. This piece rests precariously, though solidly on the flat basin piece. It then leans back on the right wall of the Volcano. I can see the worst happening with this piece in an earthquake or whatnot.
Since I remove the basin piece and the Volcano Tip alot for maintence and etc., it is impossible to glue in BUT!!!!!!!......I added 1/4" ID to the right side of the Volcano and in doing so made a built in sleeve for the Volcano Tip to rest!!! I will take pictures. An earthquake will still make short work of the tank though.....
Long answer to your question, huh?!

How are the tangs doing in such a shallow tank? I know they have the swimming area.... But does the height stress them out?
I wish I had an answer for this.....I just don't know. They appear just as happy, active, and colorful as they did in my 30" tank. I wonder about this a lot. I think it will affect their growth rate/pattern more so than anything else.
I watch them all the time for signs of anything that I can notice, and never come up with anything. The Sailfin was very thin when I got him back and he has chunked up and colored up about double since he came back into my care. That wouldn't have happened if there was a tremendous issue....
That is my number one "concern" that I always run back into.
