Is my setup safe?
Most fish trouble starts in the setup, not the fish — and it is almost all preventable. Pick your fish and tick what is true of your tank. You will get a plain-English risk report: the gaps to close, the numbers to confirm, and the warning signs that mean test your water and get advice. Free, nothing saved to a server — the report shows right here.
A reading, not a diagnosis. Every check comes straight from our fact-checked care
sheets — it just reflects your setup back against what keeps that fish safe. The report always shows
on this page, free. It can't see your tank and never diagnoses; when in doubt, test your water and
ask a fish-savvy vet.
