is there a problem if my cobalt blue is not burrowing?? i've heard many people say they haven't seen their cobalts in a couple of months, and then some say they see them quite often. but all these say that the T has a burrow. mine is just hanging out on the substrate and sometimes wanders on the sides of the tank. it is 2.5 inches, has a 6x6 inch and 10 inch deep container. i put about 6 inches of pure peat moss in there and there's plenty of ventilation. the substrate is not really wet, or dry. did i just get lucky with one who's always out? or is there a prob??
