Fish only tank.... Need rock?

I think you still need a media for bacteria to grow to break down the ammonia the clowns produce , you wont have to worry so much about nitrates so you could use any kind of filter.

Nope not needed. Lots of commercial fish only displays use ornaments and zero actual rock. You'll just need some sort of bio-filter.

I just used a large Aquanova 2000 canister filter filled with live rock rubble, and delivers 500 gallons an hour through the tank. Another large filter choice would be an FX5 either filter works well.

Many use a sump system and all the rock is hidden.

Perhaps but that would be unusual, typically the sump would house a bio media like ceramic or plastic bio-balls since it's more effective and takes up less space.
