Cool Weather Pond Fish Food

Pond Fish are "cold blooded", which means their body cannot regulate its own temperature. Their body temperature depends on the environment they live in!
When the water they swim in gets colder their body functions slow down. This includes their ability to digest.
They also do not have stomachs! Their digestion is entirely done with their colon, which is slowed by their lower body temperature.
Feeding the wrong kind of Pond Fish Food once this happens can lead to severe digestive problems including impaction and even death of the fish (with no apparent outward signs of distress).
Cool weather Pond Fish Food contains easily digested vegetable matter (wheat germ and/or spirulina) to prevent this from happening.
