well i am glad to hear their doing well, and yes that guy just wants your money i have a false percual clown and he is laying in my toadstool coral right now as i type. my clown play's in my two large toadstools all the time. it took him about two weeks to go to them once they were introduce to my tank. and now he stays in them alot along with other fish and inverts that like to swim through its tentalces
so i hope you have good luck with the new fish taking to the anenomes and dont rely on that guy for info, seems to me that he just trying to help his pocket book and not the great hobby of marine aquiariums.
have fun watching the new addition !!
