Fish-feeding education, not veterinary advice. Contact a fish-experienced veterinarian promptly for illness, injury, appetite change or concern. Do not wait for this note or an app answer. No feeding, fasting, treatment or safe waiting interval is supplied.
Life stage belongs in the question
PetMD and MSD describe changing needs with age or growth. That does not make guessed age, length or a shop label a reliable calculator input. This site estimates neither age nor body condition and supplies no growth ration. Ask what the actual plan is based on.

A pond is not an indoor aquarium
MSD and PetMD discuss temperature and seasonal context for pond fish. Those passages do not authorize applying a threshold to any species or system. We publish no temperature target, food-withdrawal threshold or restart date and ask for no water or equipment change.

Medical diets need actual care
A broad food article does not diagnose buoyancy problems, obesity or deficiency from appearance. This site recommends no medicated feed, supplement, live-food rescue, fast or treatment. Contact a fish-experienced veterinarian promptly when something is wrong.

Uncertainty does not establish blame
Nutrition is one part of care. A website cannot establish why an individual became ill or whether a carer caused an outcome. The question tool does not grade a household, certify a diet or claim that a fixed routine guarantees health.
