Mine would have that eaten in two weeks. A couple nights ago I had to retrieve a frag that flipped behind all the rocks and after putting things back i hadn't noticed one of my Black Codium plants got away from it's protected corner (so the hungry, hungry hippo, I mean Urchin can't get it). But the Urchin sure noticed it and after a couple hours I was heading to bed and he was braced between a rock and the glass with his mouth in mid water munching on a "tree" of Codium from the "trunk" looking like it was a tree straw. I was about to take it away but decided to just let him have it. By morning what was about a 3.5" tree, size of an orange/ ball now is a like a branch on his back.
I have to find someone with a Fern Caulerpa problem to be my friend, lol. My Urchin is a monster eater!
I am so glad you saved yours, at least now he will have a pretty good life for an Urchin.
