It's the Hermit Crab Patch's Organic Soil/Diet Supplement. Here's the description on the website:
The Hermit Crab Patch Organic Soil/Diet Supplement - 4 oz. Contains 100% organic worm castings. We offer a bowl of this supplement in our cages and find that we are refilling this dish frequently. The Castings are loaded with minerals and our crabs devour them.
Analysis: Calcium, Magnesium, Potassium, Sodium, Phosphorus, Sulfur, Nitrogen, Boron, Copper, Iron, Manganese, Zinc, 60-70 Trace Minerals and Elements.
Trace elements? Boron? Being the newbie I am I have no clue if this supplement is good for my hermies. Please help. I want to give them the best life possible and make sure they're all happy. Thanks!
