I have a group of 7 Jack Dempseys I purchased when the were 1 1/2" They are all between 3"-4 1/2" now. Three days ago I transfered them out of their tank and into a 175gal stock tank outdoors. I set up distinct territories with rock structures so everyone could claim turf and they could pair off. As of this afternoon, my Jacks are still hiding like big babies. The mighty Jacks are not moving around much other than to dart from one rock structure to another and then out of sight. I even put some feeder livebearers in there and they will not come out and chase them. So my question is how long will it take them to settle in and stop this hiding like a bunch of school girls? School girls you're braver I just couldn't think of another flip phrase.
