250 Gallon Starphire tank

I posted this elsewhere but maybe more will see it here:
I have these stupid little pest anenomes, they are about 1/4 to 1/2 inch in diameter. They are not aptasia, or majenos.
I have had them for about 2 years, but now there are a couple hundred of them.

I have tried kalking them, it works, kinda, but there is no way that I could get them all. I can't reach all over the back of my rocks, let alone see back there.
Any ideas what fish or invert might eat these?
I have a CBB from Flatlanders, that is in QT as we speak. The CBB eats aptasia, but I can't seem to get him to eat these things.
