set up a 50g-ish sized tank, throw the majano covered rock in it, and throw your copperband in there. If the copperband eats the majanos, it's a win win situation, and you don't have to worry about the anemones spreading to rock in your main tank. once the anemones are gone you move both the rock and the fish to your display tank. While the fish is in the anemone ridden tank, you can try feeding it alternative food (clams, etc). Try brine shrimp too, about 4-5 times a day. I've found 50% of the copperbands I have experience with will eat brine if it's fed very often throughout the day in small quantities.

You might even be able to cram 50 pounds of rock into a 33g if you're on a budget, and set up a cheap aquaclear HOB filter.

dont pull the coral take a razor blade and cut the stem as close to the rock as possible. you will want to try and use only one cutting motion as it decreases stress. take some wedding vail material and wrap the mushroom face up on a peice of rubble. The GSP you may be able to peel off.

Cooking rock means to have it sitting in the dark (bucket, rubbermaid container) with a powerhead and heater only. water changes aswell. you would have to dry the rock for a while first to kill everything off. after its dry you cook it. after its cooked 4-6 weeks min (no Smell) you can intoduce it to your system.
