More of the "reef safe" species...Blue Throats, Pink Tails, Durgeons, Sargassum.
Stay away from anything else (Humu, Queen, Clown, etc.) if you like your Lions.
There is no perfect Trigger. Even the less aggressive ones, like the ones I mentioned, can have a bad attitude and kill a fish when you least expect it.
It's a risk you're gonna have to take, if you want a Trigger.
I kept my 15" Volitan with everything from Clowns to Queens to Durgeons to Blue Throats and never had a problem...but, that doesnt mean you wont.
