in my experience, BTA will be the best bet to host. However, they split like crazy. I currently have 21 in my tank and cannot remove many of them without some serious work and even then it is still going to be difficult. Plus mine roam all over stinging stuff. The other issue is many captive bred clownfish seem to take longer to eventually agree to host into the anemone. I know there is some debate on who hosts who, but for the sake of this conversation we say the anemone hosts the clownfish. But my current clownfish took 2.5 years to finally accept the anemone and before I moved, my old clownfish took 6 years. Only when I tried to catch them did they go into the anemone. Some people have instant luck, just know that it isn't always that way! And good luck.
