Here's the compatibility list:
Marine Betta:
Semi aggressive. Watch it closely with the pinnatus.
Radiata Lionfish:
Aggressive. Be extra careful.
Hawaiian Dragon Eel:
With all the other fish, I might not add it.
Pinnatus Batfish:
Either remove this fish or everything but the betta, angel, and tangs.
Emperor Angel:
These guys are okay, they won't normally get too mean. Be sure to keep an eye on the adults.
Yellow Tang:
These are okay tankmates for peaceful fish, provided the aquarium is big enough. Which it is.
Chevron Tang:
These guys are pretty. And expensive. And not too mean.
Niger Trigger:
I wouldn't trust it.
Red Coris Wrasse:
They're mean. Be careful.
...But, of course, aggressive is what you're aiming for.

Here's the list of how they should go in. Ignore any fish you aren't adding:
1st gen: Add Pinnatus and tangs. Cycle.
2nd gen: Add the angel, maybe the betta. Cycle.
3rd gen. If you haven't added the betta yet, do it now. Also add the Coris. Make sure it's small. Cycle.
4th gen. Add the lion and maybe the trigger. Cycle. Wait another month.
Last gen: Add the trigger if you haven't yet. Wait extra time before adding the eel. Be safe with it.
...And please, for your and your fishes' sake, leave out a few of these! I would not recommend adding:
-The Pinnatus. They grow to 20 inches. Mighty expensive. Don't always eat. Pretty and pretty delicate. Watch out for other fish.
-The eel. This isn't necessarily a bad choice. Just... predatory.
-The Trigger. It's pretty, but reeeally aggressive.
You don't have to take my word for it, but try to be extra strategic if you're not following this or any other strategy that others may post here. Good luck.
