Same here...fought the aptaisa for months with joes juice. Worked great, but it always returned since I could not get every one.
Just purchased a copperband butterfly and a few peppermint shrimp...has been working very well so far. Over half is gone now, and even better, the copperband has taken to mysis frozen and seaweed sheet, so I wont worry about it starving after the aptasia dissapears, which it shouldnt, because i do have some in my fuge and sump, which now I will leave so it can come back in the tank and both the CBB and PMShrimp wil have it to graze on forever.
Ok that didnt make a lot of sense but I dont feel like re-typing it.
