Crushed Oyster Shell

Give your isopods a dependable source of calcium with our Crushed Oyster Shell. This natural calcium supplement helps support healthy exoskeleton development, successful molts, growth, and reproduction.

Crushed oyster shell can be mixed directly into your isopod substrate or offered separately in a feeding dish. Unlike softer calcium sources that may disappear quickly, oyster shell breaks down gradually, providing a long-lasting mineral source for your colony.
