    [size=medium]I did a lot of research on this Substrate and could only find opinions from Reptile owners. Though popular with some, quite a number of them warned about the sharpness of the substrate when wet. They also warned about the tiny pieces getting into the eyes of the Lizards and cutting them.
    My opinion would be that if you want to use it, use caution and keep an eye on your Hermit Crabs.
    Please let us know if you try it and what you think of it.

    Here is one of the write-ups that a turtle owner wrote about the "Crushed English Walnut Substrate".

    Crushed walnut shell

    At first glance, crushed English walnut shell substrate may seem like a suitable indoor substrate for allergic tortoise keepers. In general, it's not super dusty, but this may vary by the brand. The odor is noticeable, but not overwhelming.

    Crushed walnut shells are advocated by sellers as a safer substitute for sand for desert reptiles. However, crushed walnut shells are considered by many keepers to be one of the least suitable substrates for tortoises.

    The small pieces may irritate tortoises' eyes or collect in skin folds. When wet, the crushed shell pieces feel very abrasive when rubbed between fingers. In fact, crushed or powdered walnut shells are used in many skin exfoliating beauty products (rubs to remove skin surface cells).

    If eaten, the pieces may clump up and cause a potentially fatal impaction (intestinal blockage). Wet substrate can easily be formed into balls (pic) that hold their shape.

    In addition, if not changed frequently, crushed walnut shells may provide an ideal growth medium for bacteria and fungi.
