Purpose
This site provides calm, general informational content for a common situation: fish acting differently after a water change.
The goal is recognition, safety triage, and decision clarity — without panic, and without teaching actions.
What this site does not do
This site does not provide aquarium care instructions, troubleshooting steps, measurements, dosing guidance, product recommendations, or guarantees.
It also does not diagnose conditions or replace guidance from qualified professionals.
How to use the pages
Start with the Home page for recognition and calm framing. Use the Safety page if you are unsure whether the situation is urgent. Use the remaining pages for high-level context, clear observation, and neutral language for handoff if needed.
