A good combination for that tank would be
1. Snowflake Eel
2. Sharpnose Puffer
3. Bluehead Wrasse
I have kept all of these fish before and they are awsome. I still have my SFE. I traded my puffer because it was nipping at my lion and my bluehead wrasse jumped out.
for
1.Pinktail Trigger
2.Picasso Trigger
3.Snowflake Eel
4.Yellow Tang
5.Rock Beuty Angel
6.Volitan Lion
7.Zebra Moray
8.Dragon Wrasse
Before Anyone gets exited over keeping triggers with lions I bought my triggers from people who kept them with lions for about 8 months. I have everything now...
Well, Lets just hope my lion enjoyed its 20 dollar snack. And I was just starting to like it to. My Pinktail trigger must have mistaken it for a silverside. When it was dead my lion ate it.
Ditch the trigger and you will be fine with some of the smaller rays and a bamboo shark. A lion is a perfect choice for that size tank. Gasguzzler should be able to help you out with some types of sharks and rays you can do.
Can some people give me some info on these fish? Will it get along with a sfe, a pinktail trigger, a picassotrigger, a volitan lion, and a yellow tang in a 180 gallon?
Triggers are time bombs. They can be peaceful for many months and suddenly be extremely agressive in the blink of an eye. A blue-throat would do nicely in that tank.
