I started a 110 a little over a week ago, you can read what's in it in my sig. I've had JD's in the past with not a great deal of luck. They were always timid and didn't fare well in the pecking order, and were finicky eaters. Well they still are at the bottom of the pecking order (outside of the dithers), but they really have defended themselves nicely, and don't get picked on a great deal. They also have eaten everything I've thrown in the tank (Spirlunia, Plankton, cut up shrimp) (my friggin Jag is only eating pellets). I think the 2 that I have are a male and female and have started dating (or going with each other), and although not sexually mature, there is definitley some heavy petting going on.....Anyway, I'm really diggin Jack and well Jill Dempsey....
