Mexican culpera

[Hens4Fish]

Hey everyone,
I think I have mexican culerpa in my 24 nano. It looks like ferns growing, and if I pull it out, it grows evern more in other areas. I was wondering if any urchins eat this stuff. I was looking at wither long spine, or tuxedo, but not sure if they will touch it. Its not too bad, but really getting annoying. I have a fuge, but it does not rid the tank of enough nutrients to kill it. Please advise.
Thanks,
Bill

Without a picture and from the description you may or may not have caulerpa. Can you post a picture? Some urchins will eat caulerpa but not always, if it is an urchin you're most interested in hopefully someone else will chime in. My long spine didnt eat caulerpa.
