(I think) It's not a good thing; the best course of action, I suppose, is to research the specific habitat requirements of your anemone and try to create those as best you can in a certain spot in the tank, and hope for the best.
If your leather is a sarcophyton, it too is an aggressive animal, sending chemical "weapons" into the tank to protect it's area. Better notify the international inspectors! You may have to decide which one you want in your tank, and remove the other. There seems to be no rhyme or reason about which anemones and corals can co-exist peacefully in which aquariums.
Regarding the lugol's solution, I don't know who told you to add it periodically to your tank, but I would stop immediately and run some carbon to remove what's in there. Iodine in any form is very toxic to marine life in concentrations slightly over NSW levels, and if you feed your fish any sort of crustacean food, like shrimp, krill, etc, I can bet you're adding more iodine into your tank than you'll ever need. Lugol's solution is kind of an old standby medication for corals, which means it kills stuff. Good for a dip to "disinfect" coral colonies, but very bad in the general water column of a reef aquarium.
