I don't have an anemone - but to save you some money (possibly) were your clowns captive bred? If so, there is a very good chance that they will not host. Also, if you search online, certain clowns host certain anemones, so you'll need to figure out the types yours prefer to increase your chances. With that said, I had a pair of clowns that hosted in many types of corals in my tank...and refused to host in my anemone. I eventually had to sell it as it started to move and kill my corals.

Also, be sure to research and make sure you have the lighting and tank requirements for an anemone..they can be touchy.

I saw a lot of good looking ones at Coral Reef.

Toadstools are great for hosting and will not decay the way other corals will due to constant hosting.

I have two mini BTAs. ince you are willing to wait, when one splits we can work something out if you want one.  I got one originally about 2 yrs ago and that one has turned into 4. I gave one to a friend and it split in his tank. My clown is in it all of the time. I have another clown though that does not host anything.

Just let me know.
