I got an outbreak of aiptasia a few months ago and bought a peppermint shrimp. He wiped them out in about 2 weeks and now feeds regularly when I feed the tank. They are hit and miss but if you get a good one, they'll take care of them. (you may need to zap the bigger ones and leave the smaller ones for the shrimp)
And yea I'll look into getting one of those guys..
but I'm still gonna get a zapper lol
