I have a 48" 55g that's been going now for a few months. Water quality is good, ph is good, temp is good. It's stocked with 5 cobalt, 4 yellow labs, 3 rusties, 2 demasoni. Many are colored up beautifully and getting better everyday. One thing has gone backwards though. They are very shy unless it's feeding time, which is once a day in the morning. As soon as I wake up they are all over the place waiting for food, but once that's over they all go to their little caves. This is odd to me, if you go to the LFS whenever anyone goes to the tank they all cluster around thinking they are going to be fed. Does this get any better? Did I create too many hiding places?
