it may not be the conditions of the tank but the temperament of the snake. I had a young female bp who constantly struck at me and everything around her. my friend also has a young bp who is very cage protective. sometimes they might be aggressive for no reason, especially if its a young one. the best thing to do is to handle it more often with confidence. if you are confident and dont show fear you are more likely to not get bit. i did this with my female and now shes a little baby. hasnt struck in almost a year
