He closes and opens as he wishes he is kind of an awkward little guy.Looks like a nice start. How much light do you have? SPS and most clams need a bunch. I ask because the mantle of your clam seems retracted.
I just made a base that is about half the width of my tank and just started putting piece together. I didn't just randomly stack. I have about 210lbs of Live rock. I bought about 80lbs at a time. So what i did was i went through the bucket piece by piece and found a suitable place for it trying to fit them together like puzzle pieces. I had 1 piece un lodge and come crashing down however it never made it to the sand bed. that's why i have those branches out past the base of the stack. In-case a piece of LR falls hopefully it will hit a brand before hitting the sand bed and lose most of its momentum.It's looking awesome!! Just wondering, how do you pile your live rock like that, i am so nervous it is going to tumble over that i only have like 2 high..
