Does anyone have any ideas on how to remove an urchin without breaking his spines? He was about the size of a fifty cent piece when I got him, now he's the size of a volley ball and he's in a 29gal. tank.
Had the same problem a long time ago, I used a plastic bowl with lid to get him into it being very careful of the spines and transported him back to the LFS in that because a plastic bag just won't do.
