Acanthicus adonis


Acanthicus adonis
Adonis Pleco
白珍珠剑尾琵琶
The Adonis Pleco is dark brown to black with numerous white spots as a juvenile. As the fish matures, the spots fade. These plecos have slender, rough bodies, a lyre-tail, and a pointed snout. These fish are omnivores, and will feed on anything from fruits and vegetables to bits of frozen meaty foods. Driftwood is also appreciated for grazing. Adonis Plecos grow to be rather large, and require adequate space. They are community safe, but may become territorial towards other plecos. 
Hard to mistake with any other loricariid other than perhaps Acanthicus hystrix when adult. Quite slender in relation to body length, even delicate in appearance when very small, although as they grow they become much more robust. Small specimens have spots over the whole body, which become bands on the caudal filaments. These spots become relatively smaller and fewer in number with growth, they are reduced to remaining on the caudal peduncle and sometimes on the leading rays of the pectoral fins. Larger adults lack white spots. When adult the pectoral fins can be in excess of 15 cm in length, giving a remarkable front profile. Acanthicus adonis is distinguished from all other congeners in having a juvenile coloration of white spots, a more pointed (vs. rounded) snout, and reduced odontodal growth on the snout margin and the preoperculars. The original description also alludes to additional color differences (pitch black for A. adonis and dark brown for all other Acanthicus).

白珍珠异形最吸引人的就是那漆黑体色布满着(白/黄)珍珠般的圆点,及拖着十分细长的尾线,再加上较低的价格,因此成为喜爱大型异形收集者的必收集鱼种之一。
在市场上常可见到其踪迹,从刚出生的1.5cm幼体,到50cm以上的庞然大物皆可发现。只可惜身上的斑点会随着成长而日渐褪去。
Acanthicus属的鱼并无脂鳍,算是较古老的异形鱼种,且此属的鱼都算是异形中巨人级的角色,在原始环境中都可长至70cm以上。
因此准备较大的缸子及活动空间是必要的。 此鱼对于饵料的接受度很高,无论是小黄瓜,异形专用饲料,一般沉底饲料,或肉类皆可。不过仍建议以植物性饵料做主食。成长速度颇快。头部可明显发觉斑点并无随着成长而增加。
