I just found beautiful Rufio, my male concinnus, dead in the tank. Luna was out exploring this morning and when I couldn't see her boyfriend I went on a search and found him underneath the slate. Yes, I take complete responsibility for my own stupidity! I changed the viv a few days ago and after scrubbing everything I replaced the plates, but mine aren't sealed into the tank as I thought they'd be easier to clean. I was sure I had secured them, but Rufio managed to get himself underneath and obviously not back out again.
I am so angry with myself and really feel like giving up. Losing the snakes is always so heartbreaking and maybe I just shouldn't be allowed to have them.
