I sometimes feed my invert-only tank with frozen oyster bits and my shrimps, crabs and others seem to love it.
But I read online that oysters are quite high in copper content which got me worried. Some say 1.3mg per 100 grams, others say 7mg per 100 grams. I don't know which is right but it is generally considered to have relatively high copper content. I also read bivalves often tend to have more copper in them compared to other seafood.
Is this something I should be worried about? Could copper in them accumulate in the tank over time and harm the critters? Should I stop feeding them oysters?
