It depends on what level of difficulty you want to deal with. Also, you say BTS, did you mean BTA (bubble tip anemone)? BTAs are widely considered the easiest of the anemones to care for and false percs will take to them. Carpets are definately a nicer anemone, IMO, but apparently are a bit harder to keep in captivity. As for tank bred clowns not hosting in an anemone, that isn't always true. You have a better shot at WC taking to an anemone but tank raised will also. Also remember, even WC clowns aren't guaranteed to take to the anemone and if they do, it can take quite some time. It took my WC SI percs almost 4 months to take up with my GBTA.
