Bulldozing urchins

[jerrberryjerr]

Any advice out there on how to keep coral frags attached to substrate with urchins? I practice the glue, apoxy, glue method and still finding frags lying on the sand in the mornings. Love my urchins and would hate to remove them. So effective in algae control…pretty fascinating in their own right too!

I've been considering rehoming my pencil urchin over this, he bulldozed and injured my nepthea a few times... he's left it alone lately, but I don't want him destroying my euphylia or bubble tip either.

I gave up, and moved all urchins to one tank….so following for ideas also
