Not sure but think aptasia x will not work. with super just use a long probe of some sort, get a good glob of it on the end and then shove it right in their mouth. they will close up around and seal them selves shut. Kalk paste is also really effective and will literally melt them away. Just mix some kalkwasser with a small amount of water to get a think paste, turn off all your pump, then use a syringe and apply a good coating to it. Let it sit for about 30 min and then turn your pumps back on. When you turn the pumps back on though make sure that none of the kalk paste that comes loose lands on any corals or it will burn them
Also keep in mind that like apisatia, for every one you see there is likely 3 that you dont, so keep your eyes open for more of them
