Goldfish are gregarious, displaying schooling behavior, as well as displaying the same types of feeding behaviors. Goldfish have learned behaviors, both as groups and as individuals, that stem from native carp behavior. They are a generalist species with varied feeding, breeding, and predator avoidance behaviors that contribute to their success ...
A mature goldfish is more likely to eat directly from its owner's hand without evident hesitation. While this behavior is welcomed by goldfish owners, it may be problematic in outdoor ponds where predators may eat such friendly prey. Mature goldfish will also explore their surroundings through nibbling or grazing behavior.
It has also been proposed that swimming in groups enhances foraging success. This ability was demonstrated by Pitcher and others in their study of foraging behaviour in shoaling cyprinids. [17] In this study, the time it took for groups of minnows and goldfish to find a patch of food was quantified. The number of fishes in the groups was varied ...
Nymph goldfish - It is similar to the fantail, except they have a single caudal fin and anal fin. Considered a byproduct of the breeding process due to recessive genes handed down from fantail or veiltail parents. Tamasaba goldfish (or Sabao goldfish) - It is similar to the ryukin, except they have a single caudal fin and anal fin. A rare type ...

Goldfish has just announced that it's embracing its more mature, sophisticated side with a fitting new name. As of today, Goldfish will now be known as Chilean Sea Bass crackers.
Examples of such cooperative behaviors include better mate finding, environmental conditioning, and group defense against predators. As these mechanisms are more-easily observable in the field, they tend to be more commonly associated with the Allee effect concept.
