※ 引述《CcccBon (希蹦)》之銘言:
: 剛剛在魚店看到紅蓮燈
: 1隻30 買5送1
: 想想也太貴了吧
: 雖然每隻都超過2公分但也沒到3公分的
: 在台中
: 巴西野生真的有那麼貴嗎?
: 不爭氣得我還是買了T_T
我沒有要談價錢,只是因為提到「巴西」,
所以講個曾經在蝦米引發討論的「巴西紅蓮燈」與「哥倫比亞紅蓮燈」。
版友如果有特別留意紅蓮燈的話,可以發現市面上的紅蓮燈可以分為兩種,
一種是正常一般的,
另外一種是藍線特別短的。
一般依約成俗會把
「一般版」的稱為巴西紅蓮燈,
「短線版」稱為哥倫比亞紅蓮燈。
這兩個地方不見得就是兩種表現不同的紅蓮燈的差異來源
(沒有人能證明短線的就一定是來自哥倫比亞,一般的必然來自巴西),
只是慣例上被用來作為劃分的名詞,
如果不喜歡,還是可以稱為短線版、一般版。
兩種紅蓮燈的表現在這篇文章中說的非常清楚:
Two forms of the cardinal tetra are known, one from the Rio Negro basin
[the "Brazilian" form] and one from the upper Rio Orinoco basin in Columbia.
In the late 1990's, Dr. Jacques Gery suggested that they might differ
morphologically, and be distinct species, sub-species or variants; more
recent studies are suggesting the latter. They are outwardly recognizable
in three ways. On the Columbian form, the neon line ends at the adipose fin,
the red colouration does not extend as far under the belly so there
is slightly more white, and the fish is chunkier in general build. By contrast,
the neon line on the Brazilian form extends below the adipose fin and
is straighter in appearance, the red extends slightly further down on the
belly, and the fish is more slender and thus appears longer than the
Columbian form.

簡單說,兩種的差別在於:
1.藍線長度:巴西可以拉到脂鰭,哥倫比亞在脂鰭與背鰭中間;
2.紅色部分:巴西線填滿腹部下方,哥倫比亞紅色不會填滿,腹部會有點白
3.體型:巴西線看起來比較修長;哥倫比亞看起來更厚。
我們一般比較常看到的都是巴西版,
短藍線的哥倫比亞版比較少看到,
若按照物以稀為貴的邏輯,
應該是在魚缸上標上哥倫比亞字樣者可以開比較高的價錢才對,
不過我們看到店家多半是特別標上巴西字樣,然後開比較高,這就比較奇怪了。
可能在水族上巴西聽起來就比較厲害吧,
就跟家電冠上德系、民宿打著歐風是一樣的道理 XD
