Ive been having luck with aptaisa-x. takes forever but its working

One option is just keep a container of vinegar with needle/syringe next to your tank. Every day zap a few Aiptasia, at the same time you are carbon dosing your tank with vinegar. It is quick and easy if you just stick with it.

Have you seen the Coris wrasse eat the shrimp or did they just disappear?

The reason I ask is that there are numerous other causes for shrimp to disappear. If the Iodine level is too low in a tank the shrimp will not be able to molt properly and will die off. With live rock and corals you never know what is lurking in the dark corners of your tank and comes out at night for a snack.

I have used Peppermint shrimp numerous times to clear out aiptasia farms. I feel that they work better as they are able to get more of the aiptasia off of the rocks than fish are.

Cheers,
