What is the best way to get rid of tulip anemones ?I Seem to have a lot if them on one of my rocks?
I would say that if it is a rock that can be removed and has no other things you want to keep alive in/on it then just take it out and soak it in some hydrogen peroxide for about 20 minutes. Then take out the rock rise it really well with some RO water and put it back in the tank after everything falls out of the rock dead.
Do you have a picture of these?
