So some of you may know I overdosed All For Reef and severely spiked my Alk. During this time my Pin Cushion urchin lost a large chunk of its spikes. I was afraid he may be a lopsided urchin for the rest of his life, if he survived. Well he survived and Turns out, the spikes regrow. I don’t know why I thought they didn’t, however my experience is when they lose their spikes they’re usually dying. Anyway couple pics of the mini-spikes
