Yellow with black spot? A foxface?
Another flame or other angel. Feed them well help decrease possibility for coral nipping. What is the outer fish in the tank. Yellow with black spot? A foxface?
Looks like a Foxface to me Minh.
I would highly recommend a Centropyge angel. Flame's are usually semi-aggressive, but you have fish in there that can hold their own.
How big is your tank? Blue face like in your Avartar or Regal angel would be nice if your tank is big enough. I always have luck, and love, Flame angels but flameback or Cherub angels also work well. I would add a pair instead of one. Open tank so Wrasses are out of the question, other than possible Leopard Wrasse pair.
I am using a phone so I did not see your tank picture well. I was thinking you have a Crispa anemone instead of a elegance angel.
Thanks on the comment on the boys. The Avatar picture was an old picture. My oldest is 18. He is at West Point right now.

I may consider Anthias. They need to feed tho quite often.What about some Anthias?
The Hawks are aggressive. I had one that killed a wrasse.There's no red fish in there! You need a flame hawkfish. Lots of personality, very reef safe, gets along with all other fish, and I second the suggestion of a pair of clownfish. No maroon clowns though. Too aggressive.
does size matter? if not I would get 2 or 3 yellow clown gobies to perch around very cute and fun to watch and look for
