How much rock you got in there? That'll help determine a CUC size IMO
. Otherwise, I'd do 2 hermits and 2 snails and a goby and wait for two weeks to make sure evrything is doing well (critters, water chemistry), then think about your pair of clowns.
You're gonna have diatom blooms soon. Look it up. You might not want your coral to go thru that. The diatoms'll go away in short time. If the water is still stable thru that, then think about your clown pair maybe.
And get the Garlic Guard ASAP to soak food for all the fish as it helps with their immune systems.
