I have 3 beautiful feather duster's well today my long black spine sea urchin decided he wanted a expensive lunch lol ...he was caught munching away on one if my dusters ! The duster did not expell his fan during the attack. Now my poor duster has slimy mucus stuff every where! Will it shed the old fan and grow a new one ? Or will it die ? or do I need to do some thing ? I am Totaly gonna trade the urchin back at my LFS!!
