Feeding a Goldfish: the honest notes
🐾
Goldfish are omnivores with no stomach: feed 2–3 small meals a day, only what they finish in 2 minutes.
🐾
They are filthy water-polluters — overfeeding is the #1 cause of ammonia spikes and sick fish. Underfeed on purpose.
🐾
Soaked pellets or blanched greens beat dry flakes; dry food swallowed at the surface can cause swim-bladder issues.
These are breed tendencies, not a prescription. For the actual amount, the calculator uses your pet's real body weight and life stage — the same veterinary formula vets use.
