Proceed if…
- You can close the main pressure gaps before setting an adoption date.
- You can use these strengths: Training need 1/5, Grooming 1/5.
- You can sustain this care setup: Plan pond volume, filtration, seasonal temperature swings and outdoor protection.
- Household members, roommates, property rules, local legality and veterinary access are confirmed.
Delay if…
- Cycling, filtration, test kits and outage/water-change plans are not ready.
- This core risk cannot be accepted or managed: Koi should not be treated as ordinary small-aquarium pets.
- Pressure points are unresolved: Space pressure 5/5, Budget pressure 4/5.
- The budget covers purchase/adoption only, not medical care, emergencies, boarding or equipment replacement.

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.
