Why FishyMag says this

The manufacturer's own wording, quoted rather than paraphrased, so you can judge it yourself.

Shrimp

Manufacturer advises against

API advises against use in any aquarium containing invertebrates unless directed by an aquatic veterinarian.

Shrimp, snails, and other invertebrates may be sensitive to this medication; not recommended for use in any freshwater or saltwater aquarium with invertebrates unless indicated to do so by an aquatics veterinarian.

Snails

Sources disagree

API advises against use with invertebrates, while some retailer listings claim snails tolerate a half dose. The manufacturer outranks the retailer here, so treat this as do-not-use unless a vet says otherwise — but the disagreement is real and worth knowing about.

Next steps

FishyMag reports what manufacturers say, quoted and linked. It does not diagnose illness or recommend a treatment, and it never infers that a product is safe from the absence of a warning — where no statement exists, it says so.

Formulations change. Always read the label on the bottle in your hand, and contact the manufacturer if your tank contains anything valuable or unusual.
