Three Second Memory
Goldfish has a three-second memory or whatever. They are actually fairly intelligent for fish and can be target trained for food. They’ll remember their keeper’s face, and studies suggest without continual reinforcement, their memories last about three months.
They’re also not ‘easy’ pets, do not belong in bowls, and really need at least a 40-gallon tank for two fancies and around a 100-gallon for two commons. They’re pond animals related to the Prussian carp. They get about a foot long.
