Otocinclus macrospilus


Otocinclus macrospilus
Dwarf Otocinclus
小精灵
This is one of the commoner "otos" seen in the hobby, and is an ideal species for the planted aquarium. Unfortunately it can be quite delicate when first imported, and losses are not uncommon. This is usually down to lack of food, as it's a small fish and needs to feed almost constantly, so it's easily starved during transportation. As almost all otos are wild caught, they can be quite sensitive to water quality, too. Many hobbyists report fewer problems if the fish are added to mature, planted tanks, where water quality is stable and there is a plentiful supply of microorganisms and algae for the otos to feed on. Once the fish are past the initial stage and are feeding well, maintenance becomes much easier.

棕灰色的身体,从眼睛到尾柄部有一贯穿的纵纹。
此鱼喜欢用嘴上的吸盘,忙碌的舔水族箱中的苔藻类。有些同类鲶鱼会吃水草,但小精灵却不会,且其体型细小,能游入极为狭小的空间,吃净苔藻,同时也可将水族箱内最使人烦恼的蜗牛卵,吃的一乾二净,进而控制蜗牛的数目,真可说是"水草箱中的清道夫"。即使如此,特的个性却十分羞涩内向,很容易在食藻时受到其它同居者干扰。加上敏感度强,因此清理表现并非很有效率。但与黑线飞狐相比它不贪饲料,专心食藻。若水族箱中缺乏苔藻类,极易死亡。
专以藻类喂食,卵生,喜好弱酸性的软水,最好饲养于密植水草和沉木并有阳光的水族箱中。性情温和,能与其它性情温和的鱼类混合饲养。
与小精灵同属Otocinclus属的还有斑马小精灵、断纹小精灵、黑精灵、红精灵等,饲养方法大同小异。
