Thinking about adding one if these beautiful creatures to my 180 but have read mixed reviews in them being out and about. I know they are mostly nocturnal but I have also read where some folks say they do stay out front and center a good percentage of the time. So thought I would see if anyone has ever had one and if so what their experience is or was. I don't mind the nocturnal part but would be nice to see a fish like that on more than just an occasion
