This week I will be buying a 33 gallon tank which messures 36x12x18. After reading some mags and articles on the internet I have decided that I will be able to keep a single JD in it without problems (many articles have said 33 is fine for a pair, but I'm not sure). I was just wondering if anyone had some tips for keeping JD's. I have heard that low lighting levels make them more at ease and also aids in showing off their colors, is this correct? Also do they need a vegetable component in their diets or are they strickly carnivors? Thanks for the help.
