stocking 66 gallon

looking for some tips with stocking my 66 gallon. bought a used setup and kept most the stuff and moved to my tank. Kept his live rock,coral,sand and about 50 gallons of his water. got a 40 gallon sump and running a fuge. He had a mandarin in it before i bought it but traded it.my tank is 48x16x20



right now i have right now a sixline that he couldnt catch so gave it to me

i want to get 2 oce clowns and eventually a bta anemone. I have to have a mandarin, whole reason i got into salt. other then that what else you guys figure would go good with these?
