The way you described the snake striking at you when you put it into "the feeding tank" makes me think its still hungry. I have a male het albino that is a vicious little s**t. He usually strikes and even if you go near his tub, hes looking out at you like he wants to strike, but since I started feeding him double it has made it rare that he actually strikes... Maybe the snake has grown and is looking for more food.... Remember that the snake just sees the heat signature of your body and might think its food...

What does the snake weigh and what are you feeding it?
