I would really like to know more about these fish eating habits, how big, cost (i know they are expensive but when im a little more experienced) or just anything you think would be important for me to know. in fenner's book its says they are one of the good butterflys and keep in mind im not getting one today, just so i can plan my tank out ( ill have a 180 by the time i get this bty)
