aiptasia and scat fish?

Stupid double post, 2 times in 2 days that happened and I swear I only clicked submit once.. it took a long time to go through, then 2 posts appear. OT: but is something going on with the forum the last couple days? I noticed one upgrade with how pictures are displayed in posts now.
 
My 75 is being attacked by aptasia and I need a big cure. I have tried peppermints and they seem to be Worthless. I get them and all they do is hide and I never see them. I try Joes and that stuff works for a short time but the stuff keeps coming back. These nudibranchs look like the cure but there is always something. I only have 4 fish an Yellow Angel, a Yellowtail Damsel, a Clown and a Coral Beauty angel. Would it really affect my tank to add a Copperband? I am tired of this stuff and it seems to be getting worse. :help:
