The Emporer Angel, I've seen tanks with Clown and Blueline triggers that the Emporer is the king. People forget about the Blueline, Clown triggers don't even mess with them, it's a mutual respect.
I started with triggers, lions, and puffers. Went into reefs, enjoyed the challenge but frankly doesn't do it for me, after about 4 years went back to my roots; and enjoy it 10 fold. I turned my 90g reef into a dwarf lion tank with an antennata, fuzzy, fu, and a zebra. I'm raising 2 baby triggers, clown and blueline. I just set up a wartskin angler tank. My 210 fowlr has a pinktail and pair of bluejaws, yellow belly dogface, tusk, majestic angel, and an orange shoulder tang. I don't even look at the corals when i go into the stores anymore.
