when putting anything in a tank w/ a trigger theres some risk, but more than likely theyll be fine. but what size tank r u going to have? for the fish ud want id suggest prolly a 75gal-80gal for what u want. if u want a volitian lion of some type like a fu manchu or something u should
have a larger tank, as they r one of the largest lions. good tank mates hmm, maybe a SFE, after awhile maybe a ribbon eel but be careful, they r known to be picky eater, often starving themselves. a puffer like a spiny box, blue stripe, and other toby puffers (i cant think of many names) maybe a clown of some type, scorpionfish. mako shark, jk. maybe a yellow tang, dwarf angel. ok i cant think of anything else so im just gonna say thats all.
