Goldfish Fact #1: Goldfish don’t have stomachs!
Goldfish don’t have stomachs and should therefore be fed easily digestible food in lots of small
feeding sessions, rather than lots of food at once. This is also why goldfish
produce so much waste and why you need a filter to keep their water clean.

With the proper care, goldfish can live for decades. This goldfish was said to be 45 years old.

Goldfish can tell different faces apart and are able to distinguish between
different shapes, colours and sounds.
Goldfish Fact #5: Goldfish have a memory-span of at least three months
Many people say that goldfish have a memory of just a few seconds, but this
is a myth! Goldfish have a memory span of at least three months!
Goldfish Fact #6: Goldfish can grow to over a foot long
Goldfish can be stunted by being kept in tanks
that are too small for them and where

potential size. However, goldfish can grow to be over a foot long when kept in
the right environment. Check out this massive goldfish!
