This is a pair of Madagascar Giant Hognose snakes (
Leioheterodon madagascariensis) I had over a decade ago. Absolutely awesome snakes. They "accidentally" bred for me once; the female laid around 4-5 eggs, but I was not prepared for it at all, and they had pretty much dried up by the time I discovered them in the enclosure.
I had to give them up when I moved out of state to continue my college education. They are definitely a species I wouldn't mind working with again in the future.
