I have a 125G FOWLR and want to get a 2-3 in. clown trigger. I currently have a 2-3in. Picasso trigger and about a 1-2 in. Niger trigger. I also have a powder blue tang (King of the tank), yellow tang, dog face puffer, 2 small false clown's, and small elibi angel. All my fish get along except the powder blue chases and terrorizes the niger trigger. He does alright because he usually dashes into the rock's and doesn't seemed to be bothered. Personally I think if I have any problems it will be with the powder blue and the clown trigger. My LFS seems to think my Picasso might terrorize a clown trigger, but I thought clown triggers are considered aggressive trigger's while picasso's are one of the least aggressive. Does anyone have or know if a picasso will get along with a similar sized clown trigger?
