I'm really confused by this post...
Do you already have the Clown?
Do you already have the Corals?
If no to either of the first questions,
Is either one (or are both of them) en route to your home?
If no to that one and to either of the first questions, why would you choose to mix the two at this point? Patience would be key b/c both are fairly expensive and very interesting animals...
If you already have both (or will have both due to an already-placed order), disregard my queries...otherwise, hold off on one or the other until you get the tank situation resolved...it's worth it to you and your animals to do so.
