hmmm.. not sure really. maybe j/ a full belly. i don't have any blue-spotteds, but have dealt w/ their very close of kin the Jefferson's salamander. i have kept various species over the years and have never had them go into heat so to speak and have never worried too much about light cycles, etc. Only thing i have found is that salamanders are eating machines. I don't know about blue-spotteds, but Jefferson's are the most timid and shy of sallies I have kept.
