Uhmm... you didn't mention anything about lighting. Just FYI, Almost all clowns nowadays are either tank bred or tank raised... and have absolutely no idea what an anemone is for and becuase of that, odds are they won't use one. And how do you even know your tank is cycled? Did you see an ammonia/nitrite spike?
I would just like to add that you need to SLOW DOWN a bit. Do not be too anxious to add to the salt tank too quickly. There is a saying in the salt world and that is anything worth having in saltwater is done very slowly. If you rush it you are setting yourself up and your tank for a devastating crash meaning that everything in the tank will die or be dieing. If I were you I would let the tank run with some live rock for three to four weeks. After that you can test your water and see where your water peremeters are. If everything is sitting at 0 and your SG is between 1.022-1.027(this mimics seawater from the ocean) then you can add some inverts such as turbo snails or other snails and some hermit crabs perhaps. Then let it go another three to four weeks with just them and see how they do. While this is happening I would advise doing some small water changes once a week to keep the water quality where it should be. If all goes well with the the live rock and the inverts, then you can go ahead and add a pair of clownfish. I would not mix different kinds of clowns since they will most likely fight and one or two of them will end up dead. After you add the clowns, keep watching your water quality and water paremeters and do weekly water changes for another month at least before you add any other fish. Please be patient. I know it is hard but in the end you will be much happier and so will your salt tank.
almost all tomato, maroon,sabe,black,and true percula clowns will go into anenomes. only the false or oscellaris clowns wont. and yes what is your lighting you havent answered that yet. and like i said before and will once again agree with the others slow is best for saltwater. bubble tip or bulbe anemones are perfect for all clowns except the sabe which only sits in a sebe anenome.
