I noticed the yesterday that my 3 blue damsels have made little "homes" underneath my LR. It seems that they have removed a great deal of gravel to create little caves under the rock. I see them sleep in there. Has any one ever come upon this before with there damsels? Just wondering if this is normal. I also noticed some thing that looks like worms sticking out of my LR, they seem to have streched to the gravel and sift through it a night. It is amizing how much life there is at night. Everytime I look there is something different. It just keeps getting better.
