Goldfish are probably one of the most popular pets found all over the globe. The bright colors and smooth swimming characteristics make them very attractive. Beyond attraction, these underwater dwellers hide secret traits. Even those who own a goldfish or just are very fond of this little swimmer will be surprised by these ten amazing goldfish facts that might have otherwise evaded them.
Goldfish Have an Impressive Memory
Evidently, studies have shown that goldfish have a memory that lasts up to weeks and even months, rather than just the popularly known myth of a recall lasting only three seconds! Goldfish could learn to swim through hoops, recognize their owners, identify cues with feeding time, and even complete simple tasks. Their cognitive abilities are definitely above what most would have assigned them.
They’re Not Always Golden
The most common mental picture that comes to your mind of a goldfish is probably one of a handsome orange or golden hue. Goldfish do indeed show various colors: red, white, black, and even blue. It is only through their genes, diet, and light exposure that a goldfish attains its color. Interestingly enough, goldfish can even lose their bright colors gradually when kept in insufficient light.
Goldfish Can Grow Really Big
Few of the goldfishes that are kept in aquariums are too big; under a well enough environment they become really very large. In a wild or big pond, a goldfish can weigh up to several pounds and have a length exceeding 12 inches (30 cm). An 18.7-inch length marks the largest ever goldfish, showing how small their scale is based entirely on environmental influences.
Goldfish Have No Stomach
Goldfish digest food differently since a stomach is absent in them. Foods instead pass through the intestines without going into the stomach. This is why it is much more important to feed small amounts many times each day rather than one great feed. Overfeeding is likely to yield nitrogen waste and cause poor water quality in the tank and at the same time gastric problems.
They’re Descendants of Wild Carp
Wild carp, especially in the case of a type known as Prussian carp, formed the ancestor of goldfish. Later about a thousand years ago, domestication began in ancient China. Since then on, efforts into breeding have given birth to all the diverse forms of goldfish found today, from the originally single-tailed ones to fine “varieties” such as Oranda and Ryukin..
Goldfish Can Live for Decades
People have actually grown a bit of an underestimation towards the average life expectancy of a goldfish. It would seem that a goldfish has a lifespan of approximately ten to twenty years; it is reported that some have exceeded even the ages of forty! Tish is said to be the longest-living goldfish in the world: forty-three amazing client years have enriched her life. Their lifetimes can be influenced by enchantingly good and clean diet.
They Communicate Through Body Language
True enough, goldfish are totally devoid of vocal cords, yet they are amazing communicators. Messages conveyed involve movements through swimming strok and fin flicks. A goldfish could swim erringly to indicate stress or discomfort in its emotional state or flutter its fins to indicate enjoyment. Seeing their behavior will guide the owners to most satisfactorily cater to their needs.
Goldfish Can Recognize Faces
Unbelievably, goldfish can differentiate between human faces. Research has indicated that a goldfish could recognize among many the face of its owner. This ability will relate goldfish to their owners and further illustrate their sophistication in visual processing.
They’re Sensitive to Sound
Despite not having ears visible and perceptive, goldfish can hear just as well as any animal. Their swim bladder and inner ear serve to detect vibrations in water. Their surroundings should be quiet, for nearly constant vibrations or loud noises are bound to stress them.
Goldfish Are Social Creatures
These creatures reside happily in a group. While sharing a big tank or pond with other goldfish makes the fish happy, they should be compatible: the rest should be other goldfish or very compatible species, as some fish may outcompete or harass others for food.
