📚Fish authority summary
Merck Veterinary Manual centers fish health management on water quality, nutrition, sanitation and quarantine, so quiet and low-touch does not mean low responsibility.
Cycling, filtration, water changes, ammonia/nitrite checks and quarantine for new fish often matter more than interaction training.
CDC notes that fish and aquarium water can carry germs that make people sick; tank cleaning requires hand hygiene and extra caution for higher-risk people.
Low interaction does not mean low responsibility for fish: cycling, filtration, water changes, ammonia/nitrite monitoring and outage planning matter.
Educational pre-adoption screening only; not a substitute for veterinary, trainer, medical or local legal advice. Consult a professional for allergies, immunocompromise or child-safety risks.
