簡介:
金錢狗頭Tetraodon schoutedeni
自2015年起,台灣才開始有進口紀錄
產地為非洲的純淡水小型河豚
體型多在8公分以下
個性算是溫和可複數混養
與飼主互動性極佳
但捕食小魚能力不好
進口初期可餵食紅蟲或蝦子
繁殖:
飼養環境為兩呎缸混養10隻金錢狗頭
體長5-7公分(繁殖的公魚5公分,母魚7公分)
金錢狗頭跟之前繁殖的珍珠狗頭M.turgidus不太一樣
珍珠狗頭比較類似慈鯛科的繁殖方式
種魚會選擇粗糙表面下蛋
並且有護卵行為

而金錢狗頭非常類似魟魚及金魚的交配方式
由公魚叼咬著母魚併游同時刺激母魚排卵(天女散花)
開放式的下蛋方式也無護卵行為(甚至種魚會吃蛋)
金錢狗頭生出來的卵非常的小
大約是0.05mm跟鬥魚卵差不多大
目前下蛋第二天,卵開始長眼睛
(待續)
