i make a paste out of kalkwasser and cover them with it,kills them right away,in time the paste will crumble away leaving the rock aiptasia free.or joes juice.if it makes babies all over the place you will need some pep shrimp to get all the ones behind rocks.peppermint shrimps only eat the babies.i think a copperbanded will need a way bigger tank.
