Diadema urchin? Large, FREE
 

Any interest in a diadema urchin? It's outgrowing my 115g cube and the fish load is a little too high at the moment so it might be better off in a new tank.

Estimating 8" tip to tip, so, probably should go into a tank with a fair bit of free room.

Voracious hair algae eater BTW. At least has been for me.

PS. Great timing on my part to come to the conclusion I should offer him up AFTER the frag swap. Yay for me! Ugh, sorry about that.
