Unfortunately, my Rough Green snake passed away yesterday. I saw it coming, as he was looking old and like he wasn't going to make it much longer. He was a great snake, regardless of his big attitude. I'm definitely going to miss seeing him perched up in his tank watching my every move.
For now, I have no plans to fill his spot. I may just stick with my remaining two for a while. Although if something comes along that would do well in a 30g tall, who knows.
