I don't plan on doing a reef but I'll research it. I have noticed that it retracts onto the rock at night and comes back out when the lights are turned back on. The black thing with spikes relocated itself over night so I too think its a sea urchin. How do you kill it of that's what I want to do?
I don't want to kill the sea urchin, lol, I want to keep it. It's cool. It's the other stuff I'm talking about. Now I have some other critter crawling around the aquarium. Can you identify it? My son said it looks like a centipede almost.
What is this?
Yeah, they are awesome. I would set up a tank for it or trade it in. They are $50 on live aquaria. I think my LFS has one for $60-$80.
Well guys. I caught him, now I don't know what to so with him. My lfs will take him back but doesn't want to give me anything in exchange for him. I really don't have anywhere to put him so I don't know what I'm going to do with him.
