Hey guys. Just wondering if ich and other saltwater fish diseases can be spread by hermits, snails, or emerald crabs or are they only introduced on fish? I want to pick up a few more snails and an emerald crab for my 55 gal
that has cycled. Currently have two clowns,4 hermits, 5 snails. I am going to be getting a few cardinals for my QT and just want to know if I have to quarantine my inverts. Thanks.
