My new girl Freyja decided to move in her tank for the very first time since I got her, jut concerned, it was bout 2 hours ago maybe a bit more. Its from her hot side to her coldside and hasnt gone back to get warm...maybe im being overly concerned lol...how long is normal to stay on the cold side? She has bee on the hotside for days now and is in blue and due to shed... is this why she wants to cool down? Any cool side info apreciated, ty havent read much info about cool side habits.
