I've yet to have an issue moving my snakes, your opinion is cool and all but it won't change how I raise my reptiles. I do not have a large collection but experience is not based on how many snakes you have at one time.
I was stating an experience I had with tank aggression, just because you've never had it happen with yours doesn't mean it never happens with any snakes.
I don't really appreciate being attacked for how I raise my snakes, if you have a general concern over my snakes' saftey you could politely bring it up in a private message. Thanks!
