Just keep in mind, that a clown doesn't NEED an anemone, nor does an anemone need a clown...yes, it's very sweet when they get together, but neither one NEEDS the other one...
burning2nd, the drive in a clownfish to be hosted is so strong, that most will readily accept a substitute, I've seen them be hosted in corals of all kinds, frogspawn, hammer, even xenia, and mine LOVED "his" power head...
But, even most tank-raised clownfish seem to figure out what that pretty wavy thing is over there...
My TR oscellaris pair
My black oscellaris playing in the "rose garden"...there was up to 5 RBTA's and 1 green BTA in that tank, so he had his pick...yet when the anemone split, he seemed to always stay with the same piece as his "home"...but would visit the others from time to time as well...
