Looks a lot like a hydnophora sp. coral, one of the common names is a horn

Hmm. That's possible. Not one of the ones that make 3D structures
(H. bonsai, H. pilosa, H. rigida, H. grandis). But possibly one of the
flat encrusting ones (H. exesa, H. microconos). My references suggest that
it should be cream, dull green, or dull brown -- and mine is blue, which is
a bit odd.

But you've made a reasonable guess, thanks.
