Yup, just a dumb clownfish.
My larger female clown has claimed an elegance as her home. If anyone knows anything about elegance corals, they are typically found in the sand, where they bury themselves deep enough so their polyp can lay out on the sandbed.
Regardless of this, my clown clears the sand from the base every day(I usually throw it back during feeding). The elegance wasn't so happy in the beggining, but has since gotten used to it, although it does not open anywhere near as large as it should be.
Clowns are just weird sometimes.
