I'm sure it is. If you have a fish only tank, and you don't feel like using Joe's Juice, and a copperband butterfly won't touch them, get a Blue Face Angel. Mine completely wiped out my HUGE infestation of aiptasia in one week.
btw, a rock like that, around here, would fetch about $24.00 per POUND!
