Ok. Cant get any response on this on my other forum, maybe you can help! About 6 months ago i noticed a nickel sized hitch-hiker in the tank. I identified it online as a reef urchin. Not quite a long spine, more short and squat with purple spikes. Pretty neat looking guy, only comes out at nite. He is about 4 inches around right now but can fit himself into some pretty tight spots! Was looking in the tank the other nite and lo and behold... another one! teeny like the first. Havent put any new live rock in for quite awhile. Do they reproduce asexually? Are they bad for my system? Doesnt seem to do much harm except knock stuff over at nite.... any input?
here's his mug shot!
