Written by Julia Crab Monday, 01 August 2005 – this information has not been reviewed or updated but is maintained here for archival and reference purposes.
What follows is a list of ingredients added to commercial and processed foods that may harm hermit crab health when fed.
While I believe that these substances should be avoided, there is no actual scientific proof that these are harmful. This list is being compiled as a guide to dietary harm reduction.
The key to good diet, in crabs, other pets, and people, is informed label reading.
