I was looking for Hikaria Crab Cuisine but could not find any at my Petsmart. But I did find HBH Crab & Lobster Bites but the ingredients have Copper Proteinate. How toxic is it, and are they able to eat it in minimal or to none amounts?

And is Copper also toxic to Crabs and Lobsters or just shrimp?
 
yeah, i was digging through the forums when i found copper sulfate as an ingredient on some vacation feeders i bought for my to-be snails. I was worried about my shrimp as well and apparently some companies use copper proteinate, some use copper sulfate but at such low amounts, both should be safe.
