Goldfish is a beautiful tiny kind of fish.
Goldfish is one of the most distinctive kind of fishes. Let’s find out more about it!
- The goldfish is a freshwater fish.
- It belongs in the family Cyprinidae of order Cypriniformes.
- It is one of the most commonly kept aquarium fish and many people -especially kids- own it as a… pet!
- In fact, goldfish (along with dogs and budgies) have been kept as pets longer than any other animal.
- Over 480 million goldfish are sold every year!
- As a species, it was “born” in ancient China more.
- It was bred more than 1,000 years ago.
- Since then several distinct breeds have since been developed.
- Goldfish breeds vary greatly in size, body shape, fin configuration, and coloration.
- Various combinations of white, yellow, orange, red, brown, and black are known.
- But if you keep a goldfish in the dark, it gets… white!
- That’s because light helps the goldfish to produce pigment in their skin.
- Goldfish lives more than any other domestic fish.
- The oldest goldfish (on record) made it into his mid 40’s.
- For every year of a goldie’s life, the fish develops a ring on its scales!
- Those rings are called circuli.
- In case you need to see the circulis of a goldfish, you need a microscope.
- Goldfishes are able to see more colors than… humans!
- The human eyes can see a combination of the 3 primary colors (green, red, and yellow), whereas goldfishes are able to see the combination o 4 primary colors.
- For instance, they can see ultraviolet light.
- This helps them see movement in the water and find food easier.
- The 3-second memory thing is a total myth.
- Goldfishes have a sixth sense!
- You may have noticed a row of tiny dots down each side of your goldfish.
- That’s an actual organ and it’s called the “lateral line.”
- It can actually give a goldfish the ability to feel pressure changes in the water like vibration and currents.
- A goldfish will eat whatever fish fits in their mouth.
- No exceptions- that includes their own babies.
- They will even eat their own poop, so when we say they can eat anything we mean literally anything.
- You can tell a male goldfish by the breeding stars.
- Scientists don’t know why these breeding stars are on their skins.
- Some people though believe they exist for impressing females.
- Goldfishes can recognize faces, shapes, colors, and sounds!
- When given a goldfish as a gift, it used to be a sign of good and strong friendship.
- In Asia, it used to be a gift from the husband to his wife to their first anniversary.
- At one point in China’s past, only royalty could afford the luxury of pet goldfish.
- By using food as a reward, goldfish can learn to do all kinds of tricks like pushing a ball through a hoop, playing soccer and go through an obstacle course are just some of what they can learn!
- Goldfishes don’t have stomachs.
- Instead, they have one long intestine that does the job of digesting in different areas.
- Goldfish can’t close their eyes.
- But they sleep without closing their eyes.
