Very ripe fruit from a mango tree (Mangifera) are relished by hermit crabs. They even eat the peel and the nut safely.
With some difficulty, we were able to remove the nut from the pit without damaging it. We planted the nut (saddle-side-up) in some organic potting soil and started a beautiful house plant indoors. The plant in the photo looks a little droopy, but the leaves straightened up as it aged a bit. When it is a little older we will conduct trials on the leaves and report our findings here.
The sprout and the young plant are pictured here:
