This article is no longer being updated. Please use the new, comprehensive hermit crab food list! Written by Julia Crab (Kerie Campbell) Wednesday, 28 September 2005. Updated by Stacy Griffith 2016.

Fruit bearing trees are generally considered unsafe. (Not necessarily the fruit but wood, bark, leaves, seeds.) Safe WoodsRead More →
