Super bad news.

He drowned himself this evening while I was at work. My girlfriend opened his tub at about 8 to see him star-gazing. She came back at 9 with a friend to show him and he was head-under in his water bowl. He let out a couple bubbles (last breath) and gave a tail flick and he was gone. He had a vet appointment for 8:50 am tomorrow and even pooped this evening (or released his bowels upon deceasing). My girlfriend is obviously distraut after walking in on such a display and I'm rather unnerved myself. I'll be the first one in the store we got him at in the morning, dead snake in hand.

I don't know that I'd recommend leaving them fully alone every week until they feed much anymore.
