DevilDuck Posted December 16, 2021 Share Posted December 16, 2021 I have a pencil urchin that has been living in my refugium for a few months. It's "spikes" went from blunt tubes and now they are sharper and pointer. Is this normal? The refugium is full of ulva sea lettuce and grape calpura. 1 Quote Link to comment
