Evidence decisions
The whole-tank check: why one reassuring verdict is not enough
A repeatable way to include every relevant group without letting unknowns disappear.

Start with an inventory, not the product headline
List the inhabitants already present before looking at a treatment’s verdict. FishyMag separates shrimp, snails, plants and other supported groups; the checker also includes the biological filter when a livestock selection is made. A statement covering one group is not transferred to another. The site’s group labels are an organising aid, not species-level certification.
Treat missing answers as part of the result
Consider a hypothetical record with a positive plant statement and no shrimp statement. For a planted shrimp tank, the unknown shrimp answer remains unresolved. Hiding it because the plant row is reassuring would change the meaning of the evidence. Similarly, an empty selection supplies no basis for an affirmative tank-wide result.
Take the unresolved groups forward
Use the tank profile to keep the same group selection while examining different formulations. Export the result and add exact species when contacting the manufacturer. Do not interpret the least restrictive row as the overall answer or remove inhabitants from the checklist merely to obtain a positive headline. A restricted result is a prompt to resolve the evidence, not a recommendation to relocate animals or choose a substitute treatment.
Put it into practice
Your checklist
- Inventory all relevant groups first.
- Keep unknowns visible alongside positive statements.
- Include exact species in any follow-up enquiry.

This article distinguishes manufacturer statements from FishyMag’s own workflows and arithmetic examples. Linked formulation records retain their own evidence dates; publishing this article does not refresh those records.

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.
