RIP - Old friend

Well, after 11 1/2 hears, my very first fish - one of a pair of percula clowns - died on Friday. I was sad to see her go. She and her mate were the very first fish I put in my tank back on Thanksgiving weekend 2003. Her mate died about 4-5 years ago. It was a great fish -very docile.

So now I'm left with a single male percula (I've had him for 5 or 6 years) in my 75 g display tank.

I really want to move my fancier pair of snowflake clowns from my frag tank to the Display tank.
So, do I
1) Leave the percula in the Display tank and add the pair of snowflake clowns (Would all 3 get along?)
2) Move the percula to my cube tank - to be paired with a black onyz clown
3) Move the percula to the frag tank

What do you think?
