Titan, Queen, Blueline, Undulated trigger, shark has no chance. The ocean may be different, but in an aquarium the trigger would win, with almost no matter the size difference. Most people say triggers are not that mean and blah blah blah, yea go on with your bad niger trigger and picasso.... lmao. Nurse shark with a REAL trigger, no chance. In the end its just an overall bad idea, i just hate these people who say i have had triggers and they are not that aggressive. " My niger trigger wasn't mean at all! Triggers are not as mean as everyone thinks". LoL its purple for god sakes what do you expect!?
