alot of people on here think they know about triggers but they dont, i have alot of expierence, with them, i even asked questions about them to see how people responed, as i do on every forum, play the dumb newbie, ok here the deal, blue lines are mean sob's, the blue line and clown trigger are debatable when it comes to whos the boss of who, sometimes ull get a beast of a blueline, and sometimes expecialy after they hit adult hood ull get a extremely mean clown fish, that would tear a blueline in half, clowns seem to bite at everything that gets close to the tank, even the tank sometimes, bluelines are a little bit more people shy, but gett bigger than clown triggers, and in return are more dominant than clown triggers, anyways u have a badd ass trigger one of the baddest, the baddest trigger u can get is a titan, and also the queen in second, ive read some of your other post, and yes u can keep triggers in the same tank as long as u have a **** load in the tank, they call it clouding, but thats stupid and dumb and makes your tank look retarted cause u have a gang load of fish in it, if i were u, id get a grouper of some type, the thing is triggers dont like other triggers, fish look at other fish and look at there shape and color, so they know damn well when there is another trigger in the tank with them, they would be less annoyed with another grouper in the tank, WHY??? i dont know that just the way these fish are, so if i were u, id get something else to live with him, u might want to get a bigger tank eventuallly though, if u raise theys guys right they will get huge.........
