Sea urchin waste
I recently added a pincushion urchin (2 months).
It’s been a character... I have had to glue down all my frags. It still sometimes agitates corals. But they always open right back up.
So for now I’m keeping it.
My question was about its waste. I noticed it dropping little flake like pellets right onto my hammer coral.
Is that the waste (poop) or is it just like processed rock/sand?
