which ever one decides to kill all its tank mates would be the one i consider to be the meanest becuse each fish have thier own personalities just like dogs and humans.. some have reputations of being the tank jerk and some have reputations of being mellower but i dont know of a single triggerfish that can read the forums to know what reputation they are supposed to live up to
I currently have a clown trigger and a niger trigger and both are mellow and even leave the mollies alone at present, will they be diffrent in 5 minutes or 10 years i dont know only time will tell if my triggers stay mellow or if they go on a murder rampage
clow is aprox 7 inches and introduced at about that size and niger is about 3 inches and introduced after the clown trigger so who knows but all has been fine for the last couple months..we will see what its like in 30 seconds or 10 years if /or things change
