In smaller tanks (60g or less) peppermint shrimp have 100% worked for me, in my larger tanks matted filefish (takes them awhile but usually within a couple of months will get rid of it) and CBB's got rid of the aiptasia. However if the shrimp/filefish or CBB dies the aiptasia starts to come back within a few weeks to a month.

My vote:

Peppermint shrimp - success (they don't all eat Aiptasia, so adding a few from different sources works better)

Joe's Juice - success

Matted Filefish - success

Kalk paste - success (just killed a few a couple days ago)

I found it pretty easy to control them in my smaller tanks but once I stepped up to a larger tank it became much more difficult. Manual control was impossible, even with what I considered to be minimal aquascape I just couldn't reach everything.

Matted File Fish solved the problem for me but I went through three of them before I found one that would tackle the. It still took several months for him to start eating them. You have to be patient.

Alot of stores cant really tell the difference from peppermint shrimps and camelback shrimps. Those with no success with the peppermints might want to take that in consideration. But I voted copperband butterfly for aptasia.

Filefish worked for me. But after removing it. Aptasia came back

I'm currently in the process of culturing Designer and Limited Edition Aiptasia. These are species that you won't find anywhere else and will be highly sought after. Don't be fooled by imitations!

I'll let you know how they turn out! Currently taking pre-orders.

Are they ok in the mixed reef or do you recommend species only tank?

i waited a while before adding much to the tank to see if i had any tag alongs i did find a couple and i removed that rock completley. thats my only experience with them thankfully

When people say success is that means permanent? Example matted filefish is present the aiptasia is no where in sight. If filefish is gone and aiptasia came back that mean it not a successful. Aiptasia spreads when they died.

I used aiptasia x it worked and rid my system completely
However you need to be persistent everyday if one pops up during the weeks following the first time you use it on all of the aiptasia in your tank. After about 1 to 2 months I no longer saw any more spawn up in random places. So you really have to tackle it for a while before you ate completely free of aiptasia
