New reef in the works, 225g

[Delphinus]

I don't know why this would be but it seems to me that they don't bore into rock in our tanks, just attach. But in the wild they are most definitely enveloped in the rock. I should try to dig up some pictures I have of them on the GBR when I was there a few years back. It's pretty bizarre looking just seeing the mantles out on the reef, no clam shells visible at all.
