Have anyone witnessed a calm triggerfish turn into a pugnacious one ? I have one 4 inches trigger for 2 years, in a 50 gallon tank along with a Mac Angel (6 inches) , an 4 inch blue tang and a 1 inch niger trigger ... all getting along well, but people are telling me that my clown will turn into a devil... is this true ? I had a vicious clown trigger before for 10 years, but since he was 1 inch he was pugnacious...so will my clown change it's current behavior ?
