Richard you are under arrest!!! Forward a frag of that coral or pay a hefty fine...your choice!!!!!
I've seen several very nice tongue corals/slipper corals at my favorite LFS. The only reason I don't have one is due to a serious lack of space!
I have heard that they can be difficult to keep and that they tend to get sort of large if kept long term. They are like a plate coral in that they like to be on the sand bed and have a moderate or less current. Plus they like a moderate to intense lighting. Best of luck with yours...it looks sweet!
Now Richard which will it be....detention or a frag or a huge hefty fine for reckless display of wanted acroporas!!!!!
