Water-quality planning reminders

  • Test water with appropriate equipment; clear water can still be unsafe.
  • Let beneficial bacteria establish (cycling) before relying on the tank.
  • Avoid sudden major changes in temperature or chemistry unless guided by a professional.
  • This tool gives no chemical doses — follow qualified guidance and product instructions.

Species research reminders

  • Research each species' adult size, temperament, and whether it is social or solitary.
  • Check compatibility before mixing species — not all fish get along.
  • "Beginner-friendly" does not mean effortless; every fish has real needs.
  • Some fish (e.g. marine species) are demanding; research before buying.

Maintenance routine reminders

  • Observe fish daily and check that equipment is running.
  • Test water regularly and do scheduled partial water changes.
  • Clean filter media gently (often in tank water) to protect beneficial bacteria.
  • Avoid over-cleaning the whole tank and filter at once.

Qualified-help reminder

Fish health and water problems can worsen quickly. For severe distress, injury, rapid worsening, mass illness, or unexplained deaths, seek a qualified aquatic veterinarian or specialist. When to call an aquatic vet →

Aquarium Setup Checklist — frequently asked questions

Does this tool give medical advice or chemical doses?
No. It produces a setup and planning checklist with water-quality, species, and maintenance reminders only — never diagnosis, treatment, medication, chemical doses, tank-size legal claims, or feeding amounts. Those depend on the species and setup and should follow qualified aquatic guidance.
Is my input saved or sent anywhere?
No. The checklist runs entirely in your browser. Your selections and tick marks are not sent to a server, not saved to a database, and not recorded by analytics. Refreshing the page resets everything.
Why doesn't it tell me an exact tank size?
Recommended tank sizes vary by species, number of fish, and setup, and bigger is generally more stable. Rather than a single number or a legal claim, the checklist points you to species research and qualified guidance.
Can it tell me if my fish is sick?
No. It does not diagnose or assess fish health. For severe distress, injury, rapid worsening, mass illness, or unexplained deaths, seek a qualified aquatic veterinarian or specialist.
