- They Don’t Need a Lot of Food
These little critters are actually quite sustainable. They can go for more than three weeks without food! How’s that for a fun goldfish fact? Talk about survival of the fittest, they are little omnivores with a diet that consists of mostly aquatic vegetation, frogs (yes, frogs!), fish eggs and larvae.
Goldfish that are domesticated do well with a diet of pellet food paired with live food to help with their intestinal movement.
- 「魚餓不死，會撐死」
金魚和其他動物不一樣，只要不是時間太長，你不用擔心會餓壞它們，沒餵食的時候，它們會吸收自身的組織維持自己的生命。長期不餵餌料，魚兒會變得消瘦，但一般不會餓死。除非真的太久沒有餵食了，比如一個月。反而餵食太多會引起魚兒消化不良，殘餘飼料還會引起水質變壞，造成惡性循環而感染魚病。
- They Mean Friendship!
Giving goldfish to someone is a sign of friendship. In some cultures, a goldfish and/or coy fish is a coveted species that mean prosperity and wealth! They are also relatively easy to keep, making them great for kids and adults!
Keeping goldfish in the house in some cultures is good feng shui, bring more luck into your home. This is why goldfish make excellent gifts, they present bringing prosperity to the home of the recipient.
- 金魚象徵的意義
金魚不僅擁有漂亮的造型，再加上和平、幸福、美好、富有的寓意，成為了人們對美好的寄託。儘管我們經常認為金魚不聰明，但其他人卻將其視為幸運的動物。斯拉夫文化總是將這些小魚與好運聯繫在一起。古希臘人和古埃及人都認為金魚可以帶來好運，也可以增進人際關係和婚姻。在某人家中看到運氣好的小金魚的魅力並不少見。這種動物也是佛陀的八個神聖像徵之一，代表佛教中的生育力，和諧和財富。
金魚也可以在風水中找到。它的運動類似於磁能量，因此被認為可以帶來好運。對於提高風水數量，沒有固定的規則，但是普遍認為不平衡的數字會吸引更多的正能量。
- They Can Get Pretty Big
You might have thought these are small fish that can get quite plump. Their bulging eyes and head must account for some of their weight too. However, the largest goldfish was as large as a cat! Regular goldfish sizes are around 8-10 inches, so you can imagine how amazing that must be.
Since they symbolize wealth and luck, we assume the bigger the fish, the more luck you get. To grow large goldfish in a small pond, you should pay attention to two things: food and water temperature. They are tropical fish, so warmer temperatures stimulate their growth.
- 金魚可以比你想像中更大條
金魚會根據季節、個體差異等因素，而令魚的大小有差異。最小到最大的尺寸，差距真的可以很大。最小的尺寸大約2 – 4公分，一般的小型魚則大概8 – 13公分左右。而比較稀有的大魚，長度可以有17公分。
- They aren’t as Quiet as You Think
These little golden fish are actually quite vocal. They communicate their contentment and other emotions through subtle grunts, purrs, snorts, hoots and hums. This is heard when they’re eating too!
A big reason why goldfish do this is to communicate. Much like you and me we use our vocal chords to talk and your goldfish does so with these cute noises.
- 金魚也會發聲
魚類發出聲音是通過快速收縮肌肉，振動魚鰾來達到目的，這和陸地上的動物通過利用空氣振動薄膜發聲的方式不同。除此之外，魚類還有各種有趣的發聲方式：摩擦牙齒或者喉嚨齒，摩擦骨骼或者鰓蓋，甚至從肛門排出泡泡也能發聲。而且這些聲音還有不同的音調和音色，類似於我們聽到的咕嚕聲，敲擊聲，哈氣聲，嗡嗡聲等等。
- There are Many Types
There are hundreds of species of goldfish. Every different bulge, fin shape, color and pair of eyes can mean a different species. Of course, some are more well-known and some are just plain weird-looking.
It is widely agreed that though there are hundreds of different kinds, they fall into 5 different categories.
- 400多種金魚被分成這5個品類！
從清末至上世紀七十年代末，金魚的品種出現快速增長，已積累了數百個品種。依據金魚的外部形態的異同和親緣關係的遠近可劃分為「草、文、龍、蛋、龍背」共5大品系，至今已經形成擁有數百個品種的國粹大家族。
- The Males Impress the Females
Have you seen goldfish (or maybe even perhaps your own) develop spots around breeding time? These decorations on their gills are referred to as “breeding stars”. This happens at sexual maturity and it really impresses the ladies!
We believe the more the male grows and the more elaborate he looks, the more handsome he is considered in the fish community. Check out how handsome your goldfish are during mating season.
- 金魚開始求愛行動的前兆
- 金魚在求愛行動開始前會有所徵兆，到了求愛的季節，雄性金魚從魚鰓上側到眼睛周圍、或者是在胸鰭的周圍會出現白色的斑點，這就是所謂的「追星」。追星基本上是在求愛行動開始時出現的，不過有的金魚一年到頭都有追星存在，根據個體不同略有差異。需要注意的是，看上去跟白點病有點類似，需要注意判別。追星出現之後我們就能夠看到金魚的求愛行動了，雄性金魚開始猛烈的來回追逐雌性金魚，在產卵口附近動來動去進行交尾。
- Their Eyes are Always Open
They take keeping one eye open to a whole new level. First of all, they always have two eyes open, and that’s because they don’t have eyelids! Secondly, even when they are exhausted their eyes remain open. They might look kind of creepy floating there in a trance-like state.
- 金魚會眨眼嗎？
金魚不會眨眼，因為它沒有眼瞼 (眼皮)。眼瞼最主要的功能就是保持眼球濕潤。金魚生活在水裏，眼球本來就處在濕潤的環境中，所以不需要眼瞼。不僅金魚沒有眼睛，幾乎所有的魚都沒有眼瞼。所以幾乎所有魚類都不能眨眼，更不能閉眼。但是魚也需要睡覺，所以只能睜着眼睛睡覺了。
- They See More Colors
I guess their bulging eyes have a good use after all! Goldfish can see a broader color spectrum than we can. In other words, these creatures see more colors and have a brighter and more vivid world.
Our eyes see combinations of 3 primary colors while goldfish can see 4 (the extra one being ultra-violet). There is a reason for this, as they can see in the water better with it.
Yes, they can see more colors but their eyesight is no match for ours! The placement of their eyes (on either side) makes for a blind spot right in front of them. That’s not practical at all.
- 聽說金魚能夠看到人類看不到的東西！
金魚可以說是動物當中視力最好的物種了。金魚能夠看到大多數動物都看不到的紫外線。相信不少人都經歷過當你想偷拍金魚, 準備對焦時, 金魚突然跑掉，其實不是你不夠小心，而是金魚視力太強大了。當相機自動對焦時會發射出紫外線，我們人類的視力是看不到的，而金魚卻能準確的接收到，被突然出現的紫外線驚擾，它們要麼一下子跑掉了，要麼突然換成自衛姿勢。
