Solitary rugosan coral👍🏻

Even at that size? I have many other rugose coral pieces but they're not nearly this large in diameter. This one is almost 1.5" in diameter vs my others are 0.5-1.0" . See pic below for comparison

The one in the post above is solitary, while the rest in your link are colonial rugosan corals. I have some larger solitary pieces myself.

I also have quite a few tiny solitary rugose corals as well, so it can happen :)
