My rock boring sea urchin came on my rock well over a year ago dime size. Now, it's full grown and usually active. This week it has stayed on the sand next to the rock like it's trying to climb it, but can't. A few of it's spines on top are laying sideways. I tested my tank and everything is as it should be. I only use ro water. I've been dealing with red slime. I'm doing weekly and bi-weekly water changes to siphon the slime from the rock. Could the frequent water changes or the red slime be the problem? I also wasn't running my lights only to feed the fish. How can I help it to the top of the rocks? Tongs? Any help would be appreciated. I've grown fond of the spiny guy.
