Since bp's are nocturnal I'm not suprised that your snake has gotten huffy durring the day I try not to disturb my bp rack much at all during the daylight hours exccept for an occasional late afternoon walk to give them some natural sunlight. Oh and on the weekends there isn't much of a choice as a good portion of one of the weekend days has to be used for cleaning which I'd rather not do in the dark Durring the week water changes and handling are done in the early evening usually when I see them start to move around.
